Broil or grill tomatillo, jalapeño, and garlic until browned. Be careful to not char the garlic!
Add the tomatillos, jalapeños, and garlic in a blender or food processor with the lime, zest, lime juice, vinegar, avocado, salt, pepper, and cilantro.
Blend until smooth, serve cold with chips or on tacos, burritos, enchiladas, and more.
