Add all but the last 2 ingredients (beans and cheese) to a large pot. Stir, cover, and bring to a rolling boil.
Reduce heat to medium-low and cook, covered, for 12-15 minutes, stirring occasionally. There should be ¼ to ½ inch of liquid in the bottom of the pot when it is done.
Remove from heat. Stir in the black beans and cheese (optional). Let it rest for 5 minutes to warm the beans, melt the cheese, and absorb the excess liquid.
