1/2 c. soft butter
1/4 c. dried onion
1/4 c. mustard
1 tbsp. poppy seeds
Sliced ham
Swiss cheese, sliced

Mix. Spread on 12 to 18 hamburger buns. Put one slice of ham and one slice of cheese on each bun. Wrap in foil. Bake at 350 degrees for 15 minutes. Can be frozen before baking. Super for those "no time to cook" meals.
