Soak the black beans overnight, or for 2 hours in hot water. Drain, rinse and then add to a pot of water that covers the beans by at least 2 inches. Bring to a boil, then reduce heat to medium, cover and cook for 1.5 hours.
After the beans have been cooking for about an hour, brown the chorizo sausage with the chopped onion and chopped green pepper. As the beans finish cooking, add the chorizo sausage with veggies, 1 cup chicken broth, diced tomatoes, and ground cumin. Let simmer, uncovered, until beans have completely cooked through. Season with salt and pepper, to taste.
Prepare bread slices. Make rice for GF meal.
