1. Blend all the ingredients in a food processor or blender until you reach your desired consistency. I recommend blending it in batches since this makes a large amount of salsa.
2. Cover it and store it in the refrigerator for at least one hour before serving.
**Note: If you can't find Rotel, you can add 2-3 canned tomatoes and 2-3 tablespoons of green chilies as substitutes.
