Preheat oven to 350 degrees.
Chop onion in food processor.
Mix onion, butter, and poppy seeds together by hand, mixing until butter mixture is smooth.
Add Mustard to taste.
Open buns and spread mixture on bottom of buns.
Place ham and swiss on each bun. Usually approx. 2 slices of ham and 1 slice of cheese.
Once every bun has the butter mixture, ham and swiss spread any remaining mixture on the tops of the buns - its ok if you dont have any left, this is just to use up the remainder.
Place sandwiches on cookies sheets and cover with aluminum foil.
Bake at 350 for about 20 minutes.

When you are ready to heat them, set them out and bring to room temperature (about 20 - 30 minutes) and then bake as directed above.
