1 loaf French bread (can use sourdough or Italian loaf)
1/4 c. butter
Finely chopped sm. onion
1 tsp. dry mustard
1 tsp. poppy seed
1 pkg. Swiss cheese slices

Cut top and side crusts from 1 French loaf. Cut loaf into 1 1/2 inch slices but not through bottom crust.

Make a paste using butter, onion, dry mustard, poppy seed.

Butter both sides of slices and top and sides of the bread with the paste.

Cut 1 package Swiss cheese slices in half or 3rd's and put a piece of cheese between each slice of bread.

You can wrap and freeze at this point. Or to bake, uncover on foil. Bake 350 degrees for 18 minutes until golden - longer if frozen.
