Cut oranges in half. Scoop out the orange segments to eat alone or to use in a fruit salad. Reserve the hollow peel shells. Prepare the muffin mix according to the package directions. Fill the orange peel cups half full of batter. Wrap each one loosely with heavy duty aluminum foil. Place in hot coals, making sure that the batter side stays up. Cook 5-10 minutes until muffins are done. Adding a few cranberries to the batter adds excellent flavor and goes well with the orange. Makes 12 (use 3 oranges per package of muffin mix).
