1 stick butter, melted
2 tsp. horseradish mustard
1 tsp. grated onion
4 tsp. poppy seed
Several slices thin ham
Swiss cheese
Buns

Mix together butter, mustard, onion and poppy seed. Spread both sides of buns with mixture; put several slices ham and a slice of Swiss cheese. Wrap in foil and heat slowly at 250 degrees for 20 minutes. These freeze well; they take longer to cook if frozen.
