Step 1

Preheat oven to 350 degrees F. Place two sheets of aluminum foil next to each other on the sheet pan (these will be used to wrap up/enclose the sandwiches).

Step 2

Using a large serrated knife, slice the rolls through the center, keeping them connected on the top and the bottom. You will end up with a large piece of tops and bottoms that are still intact individually.

Step 3

Place the bottom section of the rolls onto the foil and arrange ham and cheese slices to completely cover the sweet rolls. Place the top half of the buns on top of the meat and cheese.

Step 4

In a small saucepan over low heat, slowly melt butter along with mustard, dried onion, poppy seeds and Worcestershire sauce. Pour 3/4 of this sauce over the top of the rolls.

Step 5

Wrap foil upwards and around the sandwiches and bake on a sheet pan for 15 minutes.

Step 6

Rewarm leftover butter sauce slightly on the stove or in the microwave and pour evenly over the baked sandwiches.

Step 7

Cut sandwiches into individual rolls and serve warm.
