Baked Ham and Swiss Sandwiches

This recipe comes from Becky Higgins, I don't know who she is, but Lindsay shared this recipe with me and it's a keeper. It was perfect for the birthday party because I could prepare them in advance and put them in the oven when the guests arrived so they would be hot and fresh for our lunch.
I modified her portions just a bit, so here's what I used:
*12 dinner rolls (I used Texas French rolls)
*8 slices of black forest ham (not too thick)
*8 slices of Swiss cheese
*Miracle Whip
*1/4 c. butter, melted
*3/4 TBSP. mustard
*1/2 tsp. Worcestershire sauce
*1 TBSP. poppy seeds

Prepare sandwiches by cutting rolls in half. Spread each half with a very thin (for me this is not really even visible) layer of Miracle Whip. Place ham, folded, onto bottom half, top with cheese and top half of roll. Place, side-by-side on a baking sheet. In a bowl, combine butter, mustard, Worcestershire sauce and poppy seeds. Using a pastry brush, spread onto tops of rolls. Cover with foil. You can place these in the fridge at this point if you need to or pop them in the oven to bake at 350 for 15-20 minutes, until heated through.

(picture was taken after we'd all eaten, so imagine the cheese looking fresh-melted)

My sister was concerned the sauce would make the tops soggy, but they actually crisp up and are very tasty. We were cooking for a crowd, so I figured 1 for each child and 1.5 for each adult and we ended up with only 2 left.
