You can make tacos out of almost anything. I use organic blue or white corn taco shells, or green chile tortillas
Potatoes, avacado, squash, zucchini, shrimp, red bell pepper, dried tomatoes, mushrooms.
Huitlacoche, roasted green chilies, zucchini, yellow and red peppers
Venison, avocado, poblanos, dried tomatoes, cactus paddles
