2 pkg. pre-cooked small dinner rolls
1 lb. sliced ham
1/2 lb. Swiss or Mozzarella cheese
1 stick butter, melted
1 1/2 tsp. dry mustard
1 1/2 tsp. poppy seeds
2 tsp. onion flakes
1 1/2 tsp. Worcestershire sauce

Slice rolls lengthwise without separating rolls and layer slices of ham and cheese between them. Replace tops of rolls without breaking apart. Mix spices into melted butter and spoon butter over top. Bake at 350 degrees until cheese melts, about 15 minutes. Cut rolls apart and serve.
