Saute Chorizo until almost cooked all the way through, about 6-7 minutes. Meanwhile chop your zucchini into quartered pieces. Cut tortillas into 1/2 inch wide pieces.
Preheat broiler. Add in enchilada sauce, zucchini, and tortillas. Cook for an additional 3-5 minutes.
If using cheese, top the mixture with shredded cheese and place in oven to broil for 3-4 minutes. If not using cheese, top with avocado and serve.
