Philly Cheesesteak Sliders

Place steak in freezer for 30 minutes so that the meat is easier to slice. Remove the meat from the freezer and slice very thinly. In a large saute pan, melt butter. Add in onions and peppers, and saute over medium heat until onions are translucent, about 7 minutes. Meanwhile, preheat oven according to dinner roll package instructions. Add meat to pan, and sauté on medium until only slightly pink, about another 7 minutes. While the meat cooks, put the rolls in the oven and heat according to package instructions, and heat the cheese sauce according to jar instructions. Assemble the sliders: Slice dinner rolls long-ways, and fill each with some of the meat mixture. Top each with cheese sauce. Serve warm with extra cheese sauce on the side.
