Halve the avocados, remove the pits, and scoop out the flesh. Dice the avocado into pieces roughly the same size as the tomato pieces.
Combining Everything:
Gently combine the diced avocado and tomato pieces in a medium-sized bowl. Be careful to maintain the integrity of the avocado pieces; avoid mashing them.
Squeeze fresh lemon juice over the mixture to prevent the avocado from browning and to add a zesty flavor.
Drizzle with olive oil and gently toss to coat.
If desired, add a handful of chopped fresh basil or cilantro for additional flavor.
Season with salt and pepper to taste.
Serving:
For a chilled appetizer, refrigerate the mixture for a few minutes before serving.
Serve immediately if you prefer it fresh.
Enjoy it on its own or with your favorite crackers or a slice of toasted bread.
