These quinoa and black bean enchiladas are a nutritious and protein-packed vegetarian option. The filling is made with cooked quinoa, black beans, onions, and spices, all mixed together until well combined. The enchiladas are then rolled up in flour tortillas, topped with a spicy red enchilada sauce, and baked until the cheese is melted and bubbly. Serve them with a side of Mexican salad and a dollop of Greek yogurt for a satisfying and balanced meal.
