Poppyseed Spread for Hot Sandwiches

My mother-in-law recently made sandwiches using this spread for a wedding reception.  They turned out so delicious!  You can use any combination of deli meat and cheese that you would like.  I love ham and swiss or turkey and provolone.  Make a basic sandwich on a yummy soft roll (it doesn't matter what kind or what size--you decide).  Then spread some of this poppyseed mixture on the top of the sandwich (yes, on the outside).  Bake at 350 degrees just until the cheese is melted (5-10 minutes).  You want the spread on top of the sandwich to be moist, melty, and delicious.

Okay, and now for the recipe.

Mix together:

1 T poppyseeds
1 1/2 T yellow mustard
1 stick butter, softened but not totally melted
1 T minced onion
1/2 tsp. Worcestershire sauce

This spread is enough for at least 10 sandwiches, I'd say.  So you can half the recipe, or you can store the extra spread in your refrigerator for a quick lunch or dinner any time.  It will be good for a few weeks.
