Once you're tried these ham and cheese sandwiches, you will never settle for cold ones again. Burger buns are filled with horseradish mustard, Gruyere cheese and ham, before being baked in foil.
If unavailable at your local supermarket, you can find it online.
To up this recipe to a 5 star rating: Buy a package of small sandwich rolls (actually they're dinner rolls) that are baked but are not separated. Slice the whole thing in half, horizontally. Spread first w/butter, then w/mustard, then w/mayonnaise. Cover with sliced or chipped ham, and swiss or American cheese. Wrap in foil. Place in 300 degree oven (preheated) for 15-20 minutes. Unwrap. Cool slightly. Then place on wood cutting board and cut with sharp knife. Great w/soup or as a light lunch. - 22 Mar 2003 (Review from Allrecipes US | Canada)
Great recipe! I love the combination of ham and swiss so I had to try these. The horseradish definitely gives these a nice "kick". Perfect with a bowl of tomato soup for a quick meal! - 08 Apr 2011 (Review from Allrecipes US | Canada)
Wow These were really good. The sauce was awesome. I made this recipe exactly as is. We decided next time it would be better to use sourdough bread. We are going to try buttering the bread and broiling it to make it toasty. - 08 Dec 2006 (Review from Allrecipes US | Canada)
