Preheat your oven to 450 degrees
Place your whole tomatillos, cut jalapenos (seeds removed if you're wanting less heat) and onion. I cut my onion in two quarters.
Drizzle with avocado oil and roast for 15 minutes.
Do not skip this step. Roasting these veggies gives them a depth of flavor that is important to the taste of the recipe.
Remove and transfer to a blender or food processor.
Add your avocado, spices and lime juice.
Pulse until the constancy is mostly smooth. If you need to work in batches, that is ok.
Pour into a bowl and serve with chips or add to your favorite taco!
