Chili Flavored Salsa

1 can tomatoes (28-ounce; or about a pound of fresh Roma tomatoes, peeled and chopped)
2 Serrano peppers, diced (or you can substitute 2 jalape?os, which are milder.)
1 cup of cilantro leaves
2 cloves of garlic, minced
1/4 cup diced onion
2 tablespoons of chili powder (add more to taste, if you like)
Salt to taste
A dash of sugar
Juice from 1/2 lime

Put all ingredients in the blender and blend until smooth. Taste and adjust spices if needed.
