Gather all your fresh ingredients: ripe avocados, cherry tomatoes, red onion, and cilantro.

Dice the avocados and cherry tomatoes into bite-sized pieces, and finely chop the red onion and cilantro.

In a small bowl, whisk together lime juice, olive oil, salt, and pepper until well combined.

In a large mixing bowl, gently toss the chopped vegetables with the dressing.

Let the salad sit in the refrigerator for about 15 minutes to allow the flavors to meld together.
