Combine the avocado, cucumber, red onion, cilantro and jalapeño in a bowl.
Add the lime juice, and season to taste with salt and pepper. Gently stir to combine.
Enjoy on its own or as a side to your favorite meal!
Can I make this salad ahead?
Absolutely. This salad can easily be made ahead of time, up to a day before. The lime juice prevents the avocados from browning, but be sure to store in a glass bowl (or some kind of non-reactive bowl) in the refrigerator overnight.
Can I use another cucumber other than English cucumber?
Yes! Persian cucumbers, which are smaller and with nice crunch work well. If you use regular cucumbers, you may want to seed the cucumber to remove excess moisture: simply cut the cucumber in half lengthwise and use a spoon to scoop out the soft seeds.
