Start by heating the 3 tablespoons of avocado oil in a pan over medium-high heat. Toss in chopped onion and let this cook, stirring often until the onion has nicely browned

Roast, peel and deseed peppers slice tomatillo

Add all the ingredients for the mayo and puree. Salt and pepper to taste

Mix the ground meats together and knead well so they combine cohesively. Form into balls and slightly flatten them

Let the meat cook for about 90 seconds more, then flip. While this is happening, lay the spinach leaves on your buns and tops with a little of the mayo aioli we made
