Add shredded chicken, pulled pork, and shredded beef to a dutch oven or large, heavy-bottomed stew pot over medium-low heat. Add broth, onion, potatoes, beans, corn, diced tomatoes, ketchup, brown sugar, apple cider vinegar, Worcestershire sauce, steak seasoning, garlic powder and cayenne pepper to the meats.
Simmer over medium-low heat until thoroughly heated and all flavors have had time to combine, about 30 minutes.
Serve warm with crusty bread.
Notes
This batch makes more than enough for us. We get one hearty dinner and we package and freeze the rest for another big dinner or into lunch portions. It freezes well.
