Made these ham & swiss sliders with Hawaiian Sweet Rolls. I had some brown sugar glazed spiral ham left over from Easter, that's what prompted this snack.
You cut the whole 12 rolls and start layering. Mayo, two layers of ham & swiss...
Put the top back on and make the sauce. Quarter stick of melted butter, Dijon mustard, onion powder, Worcestershire sauce, and some poppy seeds.
Pour over and completely cover the top...then let sit 10 minutes before baking. Cover with foil and bake at 350 for 12-15 minutes
Take off foil and turn up heat to 375 and brown the tops....
Cut between the lines and serve!
While all the recipes you see online for this calls for the use of deli ham, I'm not convinced it would taste as good as these. The sweet taste of the ham glaze, coupled with the buttery mustard flavor of the sauce, combined with the mayo was interesting....and way better than I thought. Worth trying if you have some leftover ham from a dinner.
