If you need a recipe that feeds multiple people that doesn't take forever to get ready and make, I suggest you test out this recipe. There is a very heavy, very dense version of this that is out on the internet everywhere that uses mayonnaise and melted butter. I wanted to make a light version that still has some of the same great flavors, and still uses the dense Hawaiian rolls that everyone loves, but is much better for you.
1 1/2 pkg. (20) King's Hawaiian Rolls, original
Stone ground mustard
1 pkg. deli style shaved honey ham (Oscar Mayer or Hillshire)
1 pkg. thin sliced Swiss cheese (Sargento)
Spray butter (Parkay)
Preheat the oven to 350 degrees. Peel the rolls apart from each other, and slice in half with a bread knife. Lay 20 bottom halves of the buns in an ungreased, nonstick 13x9 baking dish. "Squirt" and spread about 3/4 to 1 teaspoon of mustard on top of the buns. Top each bun with 1 slice of deli shaved ham, folded to fit on top of the buns. Break or cut the sliced Swiss cheese into quarters, and place 1 piece of Swiss on top of each piece of ham. Spray the inside of the top of the buns with butter spray, and place on top of the cheese. Bake for 7-9 minutes until the cheese is melted on the inside and the top of the buns are toasty and slightly browned.
