Baked ham and cheese sandwiches

I made these today for Super Bowl Sunday. I made them with brown sugar in the sauce but the kids said they were too sweet. So I'm leaving that out of the recipe. 

1 pkg Hawaiian sweet rolls (I used mini sub size)

1 pkg thin sliced deli ham

6-8 slices Swiss or American cheese

1 stick of butter

2 tsp onion powder

3 tbsp Dijon or yellow mustard

1 tbsp Worcestershire sauce

3 tsp poppy seeds

Directions:

Cut the whole sheet of rolls so you have a sheet of tops and bottoms. Line 9x13 pan with foil and place bottom sheet in the pan. 

Melt butter in microwave in bowl and whisk all ingredients except ham and cheese. Pour HALF mixture over bottom sheet in the pan. 

Layer ham then cheese slices over bottom sheet of rolls. Put top on sandwiches and pour the rest if the butter mixture over the top. 

Cover with foil and bake at 350 for 20 min. You can make ahead with sauce and keep refrigerated until ready to bake. 

Cut apart after uncovering and serve hot. Serves 6.
