Enfrijoladas can be enjoyed with or without fillings, depending on personal preference and regional variations. Traditionally, enfrijoladas are served simply with the creamy black bean sauce coating the corn tortillas, along with garnishes such as cheese, onion, cilantro, and sour cream. However, some variations of enfrijoladas may include fillings such as shredded chicken, beef, scrambled eggs, or sautéed vegetables. These fillings can add protein, texture, and additional flavors to the dish, making it more hearty and satisfying. Ultimately, whether or not enfrijoladas have fillings is a matter of individual taste. Feel free to experiment with different fillings to customize the dish to your liking!
