Lightly grease or place parchment on half sheet pans. With pizza cutter or sharp knife, divide each demi loaf into 4 equal pieces; set aside. With lightly floured surface and hands, shape each dough piece into a round. Dip each piece into melted butter and then roll in cheese. Place on prepared sheet pan (evenly separated 2-3 inches). Sprinkle with any remaining cheese. Place in warm proof box and let rise until double in size. Bake in a preheated 325-degree convection oven for 12 minutes or until golden brown. Remove from oven and brush with additional butter or oil. Serve warm.
