Step 1

Combine all prepared ingredients in a medium bowl. Add salt and pepper, to taste.

Step 2

Taste with a chip, if you're serving as a dip, so you don't oversalt it. You might have to add a little more lime juice or a little more salt and pepper. If it's too sharp with onion, add another 1/2 cup of diced tomato.

Step 3

Serve at room temperature or chilled.
