Philly Subs (Po' mans version of a Philly Cheesesteak)

The inspiration for this comes from one of our favorites-lasagna buns and something my brother-in-law said he had on his mission. I know- not an exciting story, but I am always curious how people come with recipes.
But it doesn't really matter the story, what matters is how yummy and easy this is. Once you try it, it might just become regular. I love a Philly Cheese steak. This is a simple, cheap yummy version that hits all the bells and whistles of the real deal.

Sorry-I'm not much of a measurer-so these are my closest guesses. I don't think you can screw this up too much.

Philly Subs:
Hard dinner rolls
Approx 1 lb ground hamburger
About 1/2 of a medium onion, finely chopped
1 Small Red pepper (or green pepper, or any combination), finely chopped
Two wedges Laughing Cow Original Cheese
About 1/3 of a block of low-fat cream cheese
A little bit of garlic herb feta cheese-optional*

The method:
Preheat the oven to 350. Cut off the tops of your hard rolls (electric knifes work well), and pull the middle out of each roll. Put each roll in a muffin tin and set aside.
Brown your hamburger, and when it is almost done added your chopped onions and peppers and saute until tender.
Meanwhile, start heating your soft cheeses in another pot on low-to-med until melted together. Then add to the meat mixture and stir until combined well.
Fill each roll with your meat mixture and top with the roll lid. Put a peace of tin foil over the muffin pan and bake for about 15-20 minutes until the roll starts to get crunchy and the filling is warm. Enjoy!

Any combination of cream cheese, Laughing Cow cheese, add a little feta, even melted American singles or Velveeta would work well for the cheese portion.
