Store-bought salsa is good, but homemade salsa is WAY BETTER. It's just so fresh. You can make this salsa as sweet or spicy as you want. If you are looking for a sweeter salsa, use mini sweet bell peppers. If you’re looking for a spicier salsa, use regular bell peppers, and add extra jalapeño peppers and chili powder/cayenne pepper.
If you have a Ninja or other strong blender/food processor, you don't have to do much chopping in advance. Let the blender do the work for you!
