    LOVE these Sammies! I omitted the sugar and used a little more ham! Delicious! Great method to play around with different meats and cheeses.

    I made one for myself today just to try them out. It was fabulous. I am going to make them tomorrow for a work crew at our church with chicken rice soup. The only thing I changed is I left out the poppy seeds. Thanks for the great recipe.

    A keeper. I only needed to make 6 sandwiches so I reduced some of the ingredients. I also put 3 slices of ham on each sandwich because 1 seemed like not enough. The poppy seeds clumped together so I used a knife to spread them after dabbing with the butter mixture. I used yellow mustard but honey or Dijon would be nice too.

    Mmmmm....delicious! So easy to assemble, and they taste wonderful! A guest who came over for an informal meal with us raved about them. This recipe is in my "best of the best" file!

    I used leftover slices of spiral sliced baked ham and colby jack cheese. These were really good!

    Made this many times and it is always a hit. I use slice baked ham instead of the deli ham and use half the butter mixture.

    I served these yummy sandwiches at a Baby Shower that I hosted and they were a huge hit. Everyone wanted the recipe! I was able to make them up a few hours before the shower and waited to put them in the oven until I was ready to serve lunch. The aroma from the kitchen was a big hit too!
