I had this first at Big GQ's wedding outside of Florence SC. A little old church lady gave the recipe, and told me men love it. I sure did. Here's the exact recipe she mailed me, and of course, you can use any ham with this...
Ham Delites
1 lb. sandwich ham, chipped into tiny pieces
1/3 lb. grated swiss cheese
1 stick melted butter
3 tablespoons brown mustard
3 tablespoons poppy seed
1 tablespoon worcestershire sauce
1 medium onion, grated
3 packages party finger rolls
Mix top seven ingrediants together. Slice rolls in half horizontally.. Spread mixture over roll bottoms in tins. Replace top half of rolls. Cover with foil. Bake ten minutes on 400 degrees.
