Cut rolls.  Cut slider rolls in half separating the top half from the bottom half and placing the bottom half of the slider buns in a greased casserole dish or on a baking sheet.

Make slider butter.  In a small bowl mix together melted butter, Dijon mustard, sesame seeds, dried minced onions, and Worcestershire sauce.

Cover and bake. Cover the dish with foil and bake for 10 minutes, then remove the foil and continue baking for another 5-10 minutes or until cheese is melted and the buns are golden brown. Serve hot.
