1 lb. ground ham
1/2 lb. grated mozzarella cheese
2 pkg. Pepperidge Farm party rolls
2 sticks butter
3 tbsp. poppy seed
2 tbsp. mustard
1 sm. onion, chopped
1 tsp. Worcestershire sauce

Melt butter and add all ingredients but ham and cheese. Mix well and set aside. Cut top halves from rolls and lift off. Mix ham and cheese and sprinkle over bottom half of rolls. Place tops on and pour butter mixture over rolls. Wrap in foil and bake 325 degrees for 15 to 25 minutes or until cheese melts. This freezes well before cooking!
