1/2 lb. butter, melted
2 tbsp. onion, grated
1 tsp. dry mustard
2 tsp. lime juice
1 tsp. poppy seed
1 tsp. Beau Monde

Mix altogether and cook until butter is melted and starts to boil. Pour over French bread. Cut bread into 1 to 1 1/2 inch slices, but do not cut all the way through. Put Swiss cheese in between the bread. Put in Reynolds wrap so it holds the liquid. Remove foil from top for last 5 minutes. Bake 350 degrees 20 to 30 minutes.
