Quinoa and black bean enchiladas are a protein-packed option. Cook quinoa according to package instructions. In the food processor, blend together black beans, onions, garlic, and spices until smooth. Mix in the cooked quinoa and roll up the mixture in tortillas. Top with enchilada sauce and cheese, then bake until the cheese is melted and bubbly. These enchiladas are filling and make a great vegetarian dinner.
