Cut 1oz rolls dough into half or 1.5 oz rolls dough into 3 pieces. In a medium-size bowl, mix together cheese, bacon and onions. On a lightly floured surface, shape each dough piece into a ball. Dip dough pieces in melted butter and roll in grated cheese mixture. Place 3 dough balls in each cavity of greased muffin pan. Let rise until double in size. Bake at 375º for 20-25 minutes or until golden brown. Remove from oven pan to cool on wire rack. Brush with additional melted butter if desired.
