If grilling, preheat an outdoor grill on high heat, and lightly oil a sheet of aluminum foil. If baking, preheat oven to 375°F, and lightly oil a baking sheet.
In a medium bowl, mash black beans with a fork, or potato masher, until thick and pasty.
Finely chop bell pepper, onion, and garlic.
Stir chopped bell pepper, onion, and garlic into the black beans.
In a small bowl, stir together egg, chili powder, cumin, and chili sauce.
Stir in the egg mixture and breadcrumbs into the mashed beans until the mixture is sticky and holds together.
Divide mixture into four patties.
If grilling, place patties on foil and grill about 8 minutes on each side. If baking, place patties on baking sheet and bake about 10 minutes on each side.
