Start by slicing your avocados in half, removing the pit, and dicing them into roughly 1-inch cubes. Pro tip: Make sure your avocados are ripe but still firm enough to hold their shape.

Chop your tomatoes into similar-sized pieces as the avocado. If your tomatoes are very juicy, you might want to remove some seeds to prevent the salad from becoming too watery.

In a large bowl, combine the diced avocados, tomatoes, and sliced red onion.

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

Pour the dressing over the vegetables and gently toss to coat everything evenly. Be careful not to mash the avocados.

Sprinkle fresh cilantro over the top and give it one final gentle toss.
