Mix the beef and seasoning, then add it to a glass baking pan. Press it flat so it
covers the bottom of the 9x13 pan evenly. After cooking for 20 minutes, drain the grease. Remove the beef from the pan.
Slice your rolls, so the top and bottom buns are separated into two layers. Add the bottom buns into the same baking pan. Then, top with beef, onions, cheese, and the tops of the buns.
Coat the buns with melted butter and a sprinkling of sesame seeds. Bake for another 20 minutes, slice and serve the delicious sliders.
