Directions:

In a large pan, brown the stew meat, onions and green pepper (if using) over high heat.
Add the tomato sauce (or tomato), garlic powder (or fresh garlic), cumin, salt and pepper and stir well.
Sprinkle the flour over the meat and mix well. Add the water (or stock) and mix well so there are no lumps.
Bring to a boil, cover pan and reduce heat to low. Cook for 1 ½ hours, or until meat is tender.
Taste and adjust seasonings if necessary.
Serve with rice, tortillas or mashed potatoes.
