This is one of my lazy day dinners. It is so quick and simple, and tastes great!
1 lb. deli roast beef, shaved
1 green bell pepper, finely chopped
1 small onion, finely chopped
6 slices provolone cheese
6 hoagie rolls
Heat chopped onion and bell pepper in a large skillet over medium heat for 2-3 minutes. Add shaved roast beef to the skillet just long enough for the meat to barely brown (do not overcook or your meat will be dry and chewy). Turn off heat and place provolone slices over meat. Allow cheese to melt before spooning into hoagie rolls. Spread hoagie rolls lightly with mayo if desired.
