Use your favorite beer. We used Corona.
You can change the types of cheese to anything you want -- provolone, mozzarella, or others would work too.
You can swap black beans for kidney beans or tri-colored beans.
Top with tomatoes, jalapenos, avocado, sour cream, shredded cheese, cilantro, salsa, or black olives.
The key to this recipe is to cook it low and slow. I use low to medium heat, and stir often. If you don't do this, it will burn very quickly.
Make it vegetarian, or use another meat of your choice. You can swap the ground beef for ground turkey, ground chicken, ground sausage, chicken, pulled pork, brisket, or skip the meat. You can also use a ground beef substitute. There are lots to choose from.
