* Dice the vegetables into a small, even size for the best texture and flavor in every bite.
* Roma tomatoes are ideal because they’re firm and release less liquid than larger slicing tomatoes.
* If your red onion tastes especially sharp, soak the diced onion in cold water for 5–10 minutes. Drain well and pat dry before adding it to the salad.
* For the crispest salad, season just before serving since the salt will begin drawing moisture from the vegetables.
* Feel free to add a little extra lime juice if you prefer a brighter, tangier flavor.
* If using dried mint instead of fresh, substitute 1 teaspoon dried mint for 1 tablespoon fresh mint. Crush the dried mint between your fingers before adding it to help release its aroma and flavor.
