Though you can certainly slice the squash and carrots into ribbons by hand, a julienne-style peeler or mandoline will make the job a breeze. If you want to use a peeler to julienne the squash, it is best to choose medium to small zucchini and summer squash – they should be no wider than than the width of the peeler. Also, topping these zucchini ‘noodles’ with chicken and peanut sauce is just a suggestion for a simple healthy meal, but these fresh vegetables are a great foil for tomato based sauces as well.
