3-4 Roma tomatoes, seeds and pulp removed, chopped into 1/4" pieces, about 1.5 cups total
1/2-1 medium onion (white, red, or sweet yellow all work great), chopped into 1/8" pieces, 3/4 to 1 cup total
1/2 cup chopped jalapeƱo or serrano chilies (JalapeƱos are generally milder and a little juicier.)
1.5-2 Tablespoons fresh lime juice
3/4-1 teaspoon kosher salt
1/2 teaspoon sugar
1/4-1/3 cup loosely packed fresh chopped cilantro
Optional:
1-2 teaspoons lime zest - a zippy and refreshing addition. Make sure to zest your limes before juicing them
1 very small clove garlic, grated (about 1/4 teaspoon) for that extra savory oomph
1 Tablespoon vegetable oil (unconventional, but gives extra body and helps keep all the flavors in suspension)
1/2 teaspoon to 1 teaspoon dried oregano or 1 Tablespoon finely chopped fresh
