After about 2-3 minutes of cooking, add in the mushrooms. Cook for an additional 1-2 minutes, until vegetables are done.

Add a layer of beans to the corn tortilla, followed by a pinch of cheese (only should be 1/4 cup for 8 tortillas), finally adding a handful of veggies. Carefully wrap them and place them seam side DOWN in the pan. Repeat until all of your ingredients are used up!
When all of your enchiladas are assembled, cover them with 1 cup of enchilada sauce and 1/2 cup of cheese. Spread evenly. Bake for 25-30 minutes. Once finished, top with avocado cream sauce!
