Preheat the oven to 350 degrees. Arrange the buns open on the baking sheet.

Warm the beef and sauce mixture gently on the stovetop until the sauce is melted and the beef is heated through.

Spoon the mixture onto the bottom of each bun, and top with a slice of cheese.

Place the baking sheet in the oven and heat for 5-8 minutes, or until the cheese is melted and the bread is warmed through.

Serve with the coleslaw, pickled jalapenos and fried shallots on the side, or completely dress each sandwich as you see fit.
