Onion Panini Rolls

Grease a baking sheet, lightly dust with cornmeal. Divide thawed loaf into 6 equal pieces. Shape each piece into a round. Place rolls on baking sheet 3 inches apart. Brush lightly with oil or melted butter. Let rise until almost double in size. Place a thin slice of onion on the top of each roll. Bake in a preheated 375° oven for 20 minutes or until golden brown. Remove from oven to cool on wire rack.
