6 ounces sliced bacon, chopped
3 onions (1 1/2 lb. total), coarsely chopped
2 cloves garlic, peeled and minced or pressed
3/4 C. chopped green bell pepper
1 1/4 cups red enchilada sauce
1 can (6 oz.) tomato paste
1/3 C. firmly packed brown sugar
1 1/2 tsp. dry mustard
5 cans (15 oz. each) undrained pinquito beans or drained pinto beans (see notes)

In a 5- to 6-quart pan over high heat, frequently stir bacon until crisp, about 4 minutes. Lift out with a slotted spoon and drain on towels. Discard all but 1 T. of the drippings from pan. Add onions and garlic to pan. Stir often until onion is lightly browned, about 5 minutes. Add green pepper, enchilada sauce, tomato paste, sugar, mustard, beans, and bacon. Stir often until boiling, then reduce heat and simmer, stirring occasionally, until flavors are blended, 5 to 10 minutes. Pour into a serving bowl.
