I've been craving these, so I pulled out this old recipe. If you make them on the small dinner rolls, then it's an appetizer. If you make them on sandwich buns, then it's lunch or dinner. You can't get much better than that!
Best Ham Sandwich Rolls
1 package Pepperidge Farm dinner rolls (split horizontally) or 6 sandwich buns
1 stick butter (at room temperature)
2 tablespoons yellow mustard
1 teaspoon Worcestershire sauce
1 teaspoon poppy seeds
1 pound shaved ham (I love Black Forest)
1/4-1/2 pound Swiss cheese slices
Preheat oven to 350 degrees. Mix the softened butter, mustard, Worcestershire, and poppy seeds in a small bowl until combined. Spread the butter mixture on both sides of the rolls/buns. Place the ham and cheese in the middle of the bread. Bake at 350 degrees for 10-12 minutes.
