I don't like Sloppy Joes much, but I really like this recipe.
1 pound lean ground beef
1/4 cup chopped onion
1/4 cup chopped green bell pepper
1/2 teaspoon garlic powder
1 teaspoon prepared yellow mustard
3/4 cup ketchup
3 teaspoons brown sugar
1 pinch salt to taste
1 pinch ground black pepper to taste
In a medium skillet over medium heat, brown the ground beef, onion, and green pepper; drain off liquids. Stir in the garlic powder, mustard, ketchup, and brown sugar; mix thoroughly. Reduce heat, and simmer for 30 minutes. Season with salt and pepper.
