- 1 medium-size tomato, finely chopped
- 1 small onion, finely chopped (1/4 cup)
- 6 springs cilantro or Italian parsley (leaves only), finely chopped (1 tablespoon)
- 3 serrano chilies, seeded and finely chopped; or 1 can green chili, finely chopped
- 1/2 teaspoon salt
- 1/2 cup water
Combine tomato, onion, cilantro, chilies, salt, and water in a bowl. Cover; let stand about 30 minutes before serving. This sauce is best eaten the same day, as it soon loses its crispness and flavor.
