If you don't have a balsamic vinaigrette on hand just make a quick one with olive oil, balsamic pi.ch salt and crushed garlic.
Remove stalks and gills from mushrooms, and marinate in vinaigrette for at least 20 min.
place gill side up on broiling pan and broil 3" from broiler for 6 minutes per side (adding provolone cheese after 3 minutes on second side.
