In a large skillet over high heat, brown the ground beef, onions, and bell pepper until the beef is cooked through and the onions and peppers are soft. Drain the fat and juices from the meat.

Dice the provolone cheese. Mix the diced provolone, softened cream cheese, milk, garlic powder, onion powder, salt, and pepper into the ground beef mixture. Simmer for about 3-4 minutes then remove from heat.

Cut the slider rolls in half and pile in a large spoonful of the ground beef philly cheesesteak filling into each roll.

Optional: Top with additional provolone cheese and place in the oven to broil for 2-3 minutes or until the cheese melts.

Garnish with freshly chopped parsley if desired. Serve immediately. Enjoy!
