Rather than buying tomatillo salsa already made, treat yourself with a homemade salsa. It's easy to make and super cheap. And you can control the heat, salt and acid. Toss tomatillos in the oven, blend and dip.
Place the tomatillos, onion quarters and deseeded and stemmed jalapeno in the blender, along with any juice that remains in the pan. Add the cilantro, salt and lime juice and blend until everything is pureed to perfection. If using avocado, add it now and puree again quickly.
