hamburger buns, sliced cheddar, and chopped cilantrofor serving (see note)
In a large skillet, cook the beef with 1/2 teaspoon of salt over medium heat for six to eight minutes or until the beef is no longer pink. As the beef cooks, break it apart so it's crumbled. Remove the beef from the pan and drain the excess fat.
In the same skillet, heat the olive oil over medium heat and cook the peppers, corn, and onion for four to five minutes or until they are tender.
Add the cooked beef, black beans, Manwich, salsa, cumin, 1/2 teaspoon of salt, and the taco seasoning. Stir to combine and bring the mixture to a boil. Reduce the heat to low and simmer the sloppy joes, uncovered, for 10 to 15 minutes stirring occassionally.
I love to serve these sloppy joes on buttery brioche hamburger buns with slices of cheddar cheese. Or, serve the sloppy joes like a dip with tortillas chips.
