1 stick butter
2 tbsp. mustard
1 tbsp. poppy seed
1/4 c. chopped onions
Swiss cheese slices
Chopped ham
Sandwich buns

Melt butter mix with mustard, poppy seed and onions. Let stand until thickened. Spread top and bottom of buns with mixture. Add cheese slice and chopped ham. Wrap in foil and put in oven at 350 degrees for 20 minutes. These can be frozen, if so they will take longer to bake.
