Start by preparing the ingredients. Cut the avocados in half, remove the pit, and scoop the flesh into a large mixing bowl.
Using a fork, mash the avocados slightly, leaving some chunks for texture.
Add the corn kernels, chopped red bell pepper, finely chopped red onion, halved cherry tomatoes, and chopped cilantro to the bowl with the avocado.
In a small bowl, whisk together the lime juice and olive oil.
Pour the lime and olive oil mixture over the salad and gently mix until all ingredients are coated.
Season with salt and pepper to taste.
Serve immediately in a serving dish, or chill in the refrigerator for up to 30 minutes before serving for enhanced flavors.
