This layered taco casserole is comfort food without a helping of regret. There are still layers of everything that make taco casserole great: tortillas, seasoned ground meat, chile peppers, cheese, and a mile-high topping of shredded lettuce, fresh tomatoes, avocado and green onions. But the tortillas are Primal- and Paleo-approved, the ground meat is grass-fed, and the cheese is high-quality aged Cheddar . Traditional taco casserole can be heavy and bland, relying too much on doughy flour tortillas and greasy melted cheese for flavor. To avoid this, Primal taco casserole calls for light and airy homemade tortillas and a just a sprinkle of sharp Cheddar. The tortillas are really easy to make and versatile. Use them for all your favorite Mexican dishes that need a Primal tortilla to scoop things up.
