Lentil Stuffed Summer Squash

I often wonder if I can go vegan for a day, so I decided to give it a try with these Lentil Stuffed Summer Squash. Guess what? It was easier than I thought!

I often joke that if it weren’t for my love for cheese and charcuterie, I could go vegan. But the truth is, aside from those indulgences, I already embrace vegetarian and vegan eating! I’m what I like to call a “part-time vegetarian” — at least for breakfast and lunch — and truth be told, if I didn’t have a husband and children who were carnivores, I could very well be a full-time vegetarian.

The way I approach my food is this: for breakfast and lunch, I find myself craving all my vegetarian go-tos — I start the day with overnight oats, refuel after workouts with smoothies, and I eat the same darned veggie wraps for lunch nearly every day. Sometimes I swap out a buddha bowl or my favorite chickpea or lentil salads. But even if I’m on the road or grabbing lunch with a friend, I go meatless.

Then, for dinner, I’ll cook whatever the rest of the family is craving.

I often think about how good I feel when I eat a more plant-based diet. When I consider the benefits of eating lots of vegetables, fruits, beans and nuts, I am drawn to vegan approaches to food, even if I embrace an omnivore’s diet. More and more, I like to incorporate vegan cooking into my everyday approach.

Because of this, I am really excited to partner with I Can’t Believe It’s Not Butter! to try two of their newest products: It’s Vegan and It’s Organic — these buttery spreads are made from real, simple ingredients and the goodness of plants, without artificial flavors, preservatives, or trans-fats, and are gluten-free, as well. Using It’s Vegan, I decided to challenge myself to dabble for a day in a full vegan diet. Just one day, and I already have most of the day down pat so, the real challenge for me is dinner!

Actually, the biggest challenge for me was making a vegan-friendly meal that would win over the rest of the family. With zucchini and yellow squash so abundant this time of year, I knew that Lentil Stuffed Summer Squash was the way to go!

Making the dish vegan was quite easy, especially incorporating It’s Vegan, which gave the lentil and veggie filling a buttery flavor that tasted decadent without the extra calories. Stuffed into the summer squash, I knew that my kids wouldn’t be able to resist these zucchini boats.

As far as challenges go, I have to admit that going vegan for a day was much easier than I thought it would be, and incorporating products like It’s Vegan made it so simple! The best part, though, was when my husband reached for seconds and noted, “the squash is good!” to which I replied, “Yeah? It’s vegan, you know,” smiling triumphantly.

Ingredients

For the Stuffed Squash:

  • 1/2 cup lentils
  • 1 1/2 cups vegetable stock
  • 3 tablespoons I Can’t Believe It’s Not Butter! It’s Vegan divided
  • 4 summer squash i.e. zucchini or yellow squash
  • 1/2 cup yellow onion finely diced
  • 2 cloves garlic minced
  • 1/2 cup red bell pepper finely diced
  • 1 teaspoon sriracha
  • 1/4 teaspoon ground cumin
  • 1/4 teaspoon ground coriander
  • 1/2 teaspoon white balsamic vinegar
  • Kosher salt to taste
  • Freshly ground black pepper to taste
  • Cilantro for garnish

For the Avocado Cilantro Sauce:

  • 2 cloves garlic peeled
  • 1 teaspoon Kosher salt
  • 1 ripe avocado pitted and peeled
  • 1/2 cup almond milk
  • 1/2 cup fresh cilantro
  • Juice of 1/2 lime
  • Freshly ground black pepper to taste

Instructions

Make the Stuffed Squash:

  • Put the lentils and vegetable stock in a small saucepan over high heat. Bring to a boil, then simmer for about 5 minutes or until the lentils are just tender. Be careful not to overcook as you do not want the lentils to be mushy. Drain and set aside.
  • Preheat the oven to 350°F.
  • Slice the summer squash in half lengthwise and use a spoon to scoop out the flesh, setting it aside for the filling. Take about 1 tablespoon I Can’t Believe It’s Not Butter! It’s Vegan and rub it on the squash, place it cut side down on a baking pan. Bake for about 10 minutes, until it is just fork tender.
  • Chop the reserved squash finely.
  • Heat It’s Vegan over medium-low heat in a deep sided sauté pan. Add the onion, garlic and chopped squash. Cook until the onions are translucent, about 4 minutes. Add the bell pepper, cooked lentils, sriracha, cumin, coriander, and vinegar, and cook, stirring occasionally for about 5 minutes. Season to taste with salt and pepper.
  • Stuff the squash with the filling.
  • Bake for about 10 minutes, or until the zucchini is fully tender.

Make the Avocado Cilantro Sauce:

  • In the bowl of a food processor, blend the garlic and salt until finely chopped.
  • Add the avocado, almond milk, cilantro, lime juice and pepper. Blend until smooth. If you feel the sauce is too thick, add a touch more almond milk.
  • Adjust the seasoning if necessary with salt and pepper.
  • The sauce can be prepared ahead of time and stored in a tightly sealed container in the refrigerator.

Serve:

  • Garnish with chopped cilantro and serve with the avocado cilantro sauce.

    I made this. It was fairly easy to make and delicious! I almost skipped the sauce because I didn’t have almond milk or cilantro, but I just used soy milk and a pinch of coriander, and it really added a lot of rich flavor to the dish.

    The sauce tasted like nothing but salt and garlic – perhaps reduce both by half and it might be OK. Also, there’s not enough cooking time for the squash to soften it up, and the balance of squash to lentils was not right – too much squash and not enough lentils. I seriously wonder if anyone tested this recipe before publishing it.

      Hi Susan, it sounds like perhaps the squash you had might have been on the firmer side (and perhaps larger than a standard zucchini/summer squash?) to have run into longer cooking times. I find that mine cooks up fairly quickly in the saute, and finishes in the oven. This recipe has definitely been tested, so I’m very sorry you ran into issues!

    The flavor of the lentil stuffing made the entire dish. I could eat a bowl of that and ditch the squash. I only had 3 squash but didn’t adjust the seasoning so when I do have 4 will boost up the amounts a bit because I like bold flavors.

    Second night I added an additional drizzle of Sriracha and a sprinkle of vegan mozzarella. Absolutely divine! Thanks for a flavorful and easy idea.

    I know I should be able to tell from the photos–but what kind of lentils did you use?

      Hi Frances, that’s a great question! I used golden lentils in this recipe, but definitely try your favorite. French de Puy lentils work nicely in this recipe, too! I hope this helps!

    I am thinking of making this, how long can the avo-sauce stay in the fridge without turning brown?

      The avocado sauce should be good for about a day, Jennifer! The lime juice helps it from browning too soon, though of course, the sooner you can use it, the better. Hope that helps!

    I hope you find that having a vegan meal at least a day would be helpful to your health and the health of the planet.. The list of benefits is a lot longer, but you will need to dive into it by yourself. Do your research and hopefully you will transition to this lifestyle..
    Good luck!
