Here is my favorite way of making salsa:
1 small can of Ro-Tel
1 large can of petite diced tomatoes
1 package of salsa or fajita seasoning, but only use 1/2 of the package
Cilantro (as much as you want, I happen to like A LOT!)
Salt to taste
Dump all the ingredients into a food processor or blender. . .and yummy! Homemade, wonderful salsa.
