      Everyone loves these sandwiches, the buttery topping can't be beat! I like to experiment with different combinations of meats and cheeses!

      We loved these sandwiches! They were easy to put together and delicious. I used sweet Hawaiian style slider buns instead of regular burger buns and substituted fresh minced onion for the dried version. I also used fresh minced parsley instead of poppy seeds since that's what I had on hand. These sandwiches could easily be doubled to feed a crowd. Great for parties and gatherings. We loved the sweet buttery sauce on top. A keeper!

      I used spicy brown mustard instead of regular and loved the flavor. I used larger kaiser rolls (which were really light), so I increased the amount of the cheeses and ham to make sure there was enough stuff on it. I used the exact amount of butter/mustard it required though and that seemed like a good amount. I feel like it could have used something crispy though, maybe like apple slices? I'll try that out next time. We still loved it as-is though, and was perfect as a quick weeknight dinner.

      Quick and easy supper! My family loved the sauce that topped the sandwiches. Since I am not that big on mustard, I substituted about 1/2 tsp. of dry mustard that offered a milder flavor. I also left out the poppy seeds and decreased the amount of sugar. I did not have colby cheese on hand so I substituted sharp cheddar which worked out fine. The whole pan was eaten, as well as the oven-fried potato wedges that I served with them. This is a nice way to use up leftover deli ham.

      This was a very interesting recipe. Adding the sugar to the mustard (I used spicy brown) added an interesting touch. We all liked it and it was easier for a group than grilled ham and cheese.
