Quick Chili
Serves 4

1 pound lean ground beef chuck
1 medium yellow onion, chopped
1/2 cup chopped green bell pepper
1 1/2 cups cooked pinto or kidney beans (one 15-oz. can, rinsed and drained)
2 10-oz. cans RO*TEL diced tomatoes and chilies, drained
1-2 cups frozen corn (optional)
1-2 tablespoons chili powder (to your own taste)
1 tablespoon ground cumin
2 tablespoons brown sugar (optional)
1 teaspoon salt

Combine the ground meat, onion, and bell pepper in a medium saucepan. Stirring constantly, cook over medium-high heat until the meat is crumbly and the onion is translucent, about 5 minutes. Add the beans, tomatoes, chili powder, cumin, and salt. Continue to cook and stir until the chili is bubbly, about 4 minutes.
