2 pans dinner rolls
1 stick butter, melted
3 tbsp. grated onion or onion flakes
2 tbsp. dry mustard
2 tbsp. sugar
2 tbsp. poppy seed
1/2 lb. ham, thinly sliced
1/2 lb. swiss cheese, thinly sliced

Mix together butter, onion, mustard, sugar, and poppy seed. Slice open each pan of rolls lengthwise. (If you place the rolls in the freezer for a few minutes, they cut easier.) Spoon poppy seed mixture over layers. Place a layer of ham and cheese on top, then cover with the top layer of bread. Spoon the remaining poppy seed mixture on top. Heat to melt cheese.
