I made up this recipe to use up the remaining black bean liquid and tomatoes from when I made Bean Balls
Tomato Gravy In a sauce panThe remainder of the canned tomatoes. The liquid from the can of black beans 1 cup of liquid from the remaining canned corn. 2 tbs tomato paste 1 tsp cumin 1/2 tsp mustard powder 1/4 tsp black pepper Salt (and any other seasoning you like) to taste
Stir it all up and bring to a low boil. Reduce heat and simmer for 10 minutes or until it's thick enough for you.
