1 lb. cheese, shredded
1 lb. ground ham (you could either mince, or put through a food processor if you don't have a grinder)
3 small pickles, minced (or a 1/4 cup relish)
3 T grated onion
4 T mayonnaise or salad dressing as you prefer

Combine all ingredients.  Place mixture on 12 buns, wrap in foil.  Bake at 350 F for 15 minutes.

I found this while cleaning house - I must have really liked it because I asked the person to write it out on a piece of paper for me.  Sounds easy and different.  Halve the recipe if you don't need 12 sandwiches, of course!

Enjoy
