Lettuce, tomatoes, corn, red onion, avocado, red peppers- any veggies you happen to have will do the trick!
Add a protein
Chicken, steak, cheese
Bring it all together and then add the magic touch
Heat a skillet over medium heat. Fry 1lb of chicken or steak with some onion, garlic and seasoning. Remove. In the same pan, warm 8 tortillas and fill with protein. Top tacos with 1 - 2 cups of chopped vegetables. Add the magic touch. (Choose some hot sauce, yogurt or lemon or lime juice.)
If you want a fun variation, replace the tortillas with tortilla chips and serve as nachos.
