Philly Cheesesteak Grilled Cheese

"This amazing Philly cheesesteak grilled cheese is what sandwich dreams are made of! Melt-in-your-mouth, tender and moist steak meets hot sauce, onion, peppers and cheese to make the ultimate Philly cheese sandwich! For my easy Philly cheese steak, I used flank steak that was already cooked. Leftovers work great too! You can of course use uncooked/raw meat and just toss it in with the pepper and onion and cook until done.You can also use a thin sliced rib-eye or top round steak"
