Baked Ham and Cheese Poppyseed Sandwiches

I accidentally found this recipe on a blog one afternoon- I can't remember the original location, and there are variations on this recipe all over the internet. But, I still have this one, so I always use it. Sometimes I throw on some extra meat and mix it up with both turkey and ham, etc, but the spread is what makes these so good.

 

Ingredients:

Kaiser rolls
2lb thin sliced ham
Cheddar cheese slices
1 stick butter very soft
1/4 cup poppy seeds
1/2 cup chopped onion
2 tsp mustard

 
Directions:

Blend butter, poppy seeds, onion, and mustard to make a spread. Spread on both sides of rolls. Add ham and cheese. Wrap individually in foil. Bake at 350 degrees for 20 minutes.
