Best Baked Ham and Swiss Sandwhiches EVER

These are great for any party or for lunches at home (They heat up well!). They go fast so I usually double.

Ingredients:
1 stick butter (not pictured)

2 tbsp mustard

1 tbsp Worcestershire sauce

2 tbsp poppy seeds

Sliced ham ( I use one prepackage ham, Hillshire Farm)

Dozen Hawaiian Sweet rolls (cut in half to make sandwhich)

Package of Kroger sliced Swiss cheese

Need Foil As Well

Mix the first 5 ingredients and cook for 5 mins over medium high heat (It will still be thin when done). Roll out a small amount of foil and assemble each roll individually on its own peice of foil. Cut rolls and put ham, cheese and about 1 tbsp + of sauce on each sandwhich. Wrap up the foil. Put all foil balls on a cookie sheet. Bake for 20mins at 350 degrees.
