Arrange the pork chops - side by side - on the broiler rack. Broil for 6-7 minutes. Turn the chops over and broil for 6-7 minutes. Brush the chops with some of the Burn Sauce. Broil until the sauce caramelizes on this side. Turn the chops over. Brush and caramelize that side. Remove the chops from the broiler. Allow the chops to rest for 5 minutes. Serve the chops with the caramelized onions, flour tortillas and the remainder of the Burn Sauce - on the side.
