1 loaf French bread, about 18 inches long
1/2 lb. Swiss cheese
1 egg
1 egg yolk
1/2 c. milk
1/2 c. unsifted flour
1 med. red onion, sliced

Preheat oven to 425 degrees. Cut a slice lengthwise from bread, removing top crust. With fork, scoop out soft bread, about 1 inch down, leaving bottom crust. Cut cheese into 8 cubes. Combine egg and egg yolk; mix with fork. Dip cheese cubes into milk; roll in flour, then dip into egg mixture. Place cheese cubes, alternating with onion slices, in hollowed out bread, placed on a cookie sheet. Brush outside of bread with some of milk; dust with flour and brush with rest of egg mixture. Bake 15-20 minutes, or until cheese is melted and golden and bread is crusty. To serve, cut cross wise with a sharp knife. Serve hot. Makes 6 servings.
