While meat is simmering, set the oven to broil, and place the buns on a cookie sheet. Butter each bun. Broil for just a few minutes. Watch carefully as they can burn easily.
When the meat is done use a slotted spoon to scoop it out onto each bottom bun. Place a slice of provolone cheese on the top bun. Broil for a few more minutes until cheese is melted.
Place the top bun with the cheese on top of the bottom bun with the philly cheesesteak meat.
Eat warm and Enjoy!
