Yummy Sandwiches

One package of Homestyle Rolls - cut in half. Put the bottom in a 9 x 13 pan. Top each with a slice of thinly sliced ham or turkey and a slice of cheese. Use any kind of cheese to your taste preference. We like Turkey with Pepper Jack, most of the family likes ham and swiss (although I don't know how any one can each swiss cheese).
In a small bowl or pan, melt 1 cube butter and stir in 1 1/2 Tbs poppy seeds, 1 1/2 Tbs mustard, 1 1/2 Tbs worcestershire sauce and 1 tsp onion flakes. Pour over the top of the rolls. Cover with foil and refrigerate over night. When ready to cook, put in a 275 deg oven for 30 minutes, remove the foil and cook for another 5 minutes.
