5 – 6 roma tomatoes, chopped
1 small onion, chopped
1/2 cup fresh cilantro, chopped
2 Serrano or Jalapeño chiles, seeded and minced
1 clove garlic, minced
2 Tablespoon freshly squeezed lime juice
Salt and Pepper to taste
Put all ingredients into a bowl. That’s pretty much it. I’d suggest you let it sit for at least an hour, but preferably over night. The longer, the better, as the flavors get a chance to permeate over time.
