Take bread sticks and roll them out. Cut each strip in half. Press each piece to make a square. Top each square with pepperoni and cheese cube. Press dough around filling to completely cover. Take butter mixture from the dough and melt. Dip each snack bite in butter and place seam side down on a pan. Bake for 15-22 minutes at 375 degrees until golden brown. Serve with heated warm pizza sauce.
