Place the fresh tomatoes, onion, garlic, peppers, cilantro, lime juice, 2 teaspoons cumin, 2 teaspoons sugar (if using), and salt in a food processor. Pulse until the contents are fine and well blended.
Pour in the crushed tomatoes and green chiles. Puree until mostly smooth. Taste, then add more cumin and sugar if desired. Refrigerate until ready to serve.
If refrigerated in an airtight container, this salsa should last 10-12 days.Spice Level - If you are sensitive to spicy heat, reduce the jalapenos to 1 pepper. Also, I love cumin, however, some people are sensitive to it. You can reduce the cumin to 1 teaspoon if needed.
