Philly Cheesesteak Sloppy Joes

In a pan over medium heat, brown the ground beef and drain any excess fat. Add in the diced onions and bell peppers and reduce heat to low. In a separate bowl, mix together the beef broth, ketchup, Worcestershire sauce, garlic paste, salt, pepper, and either shredded pepper jack cheese or about 1/4 block of cream cheese. Add this mixture into the beef and vegetable pan and let it simmer on low heat for 5-10 minutes. While the meat simmers, butter the soft buns and grill them on a stovetop or in the oven until lightly toasted. To assemble, place a slice of provolone cheese on each bun, then top generously with the meat mixture.
