1 stick margarine or butter (wow)
1 1/2 T prep. mustard (as opposed to making it yourself?)
1 very small grated minced onion (interesting)
1 T poppy seed
Mix together. Spread on both sides of bun.
1/2 # shaved ham
1/2 # shaved swiss cheese
Place some ham & cheese on buns. Wrap in foil. Bake 350F – 20 min. 350 might or batch lot 325F. (I think that’s what it says.)
