2 sticks butter, softened
3 tbsp. poppy seeds
1 tbsp. Worcestershire sauce
3 tbsp. mustard
3 pkgs. party rolls
Grated Swiss cheese
Sliced ham (each pkg. of rolls will need 3 pieces of the pre-packaged sandwich ham)

Mix first 4 ingredients. Slice rolls lengthwise (like layer cake). Spread both sides with mixture. Put ham on bottom half and sprinkle with cheese. Wrap in foil. Bake at 400 degrees for 10 to 15 minutes. (It helps to cut before cooking.) Let cool slightly before slicing. Even if pre-cut, they will need slicing again.
