2 sticks butter
3 medium onions, chopped
2 tbsp. mustard
2 tbsp. poppy seed
1-1/2 pound chopped ham
1 pkg. shredded swiss or cheddar cheese, 2 cups
2 pkg. Dinner Rolls

Cook onion, butter, mustard and poppy seed together until onions are tender. Split each pan of rolls in half. Spread inside of rolls with butter mixture until all is used. Evenly spread ham and cheese on top of bottom layer of rolls. Add top layers of rolls. Heat in oven long enough to melt the cheese.

Note: I use an electric knife to split rolls.
