Rough chop tomatoes, and onions and add to blender. It helps to squeeze the tomatoes and their juice to the blender.
Remove cilantro from bare stems and add to blender
Add peppers, salt, cumin, and squeeze lime juice into blender. Blend until smooth. If you like a chunkier salsa then chop everything to your liking. If you let it sit an hour the flavors are even better. Sometimes I add fresh zucchini as well.
