Forget jarred salsa -- this simple mixture of tomatoes, onions, chiles, and cilantro tastes amazingly fresh and couldn't be easier.
Stir together tomatoes, onion, chiles, cilantro, water, and 2 1/2 teaspoons salt. Season with more salt to taste.
Adjust the amount and type of chiles to make this salsa mild, medium, or hot, as you like. Salsa can be refrigerated for up to 3 days.
