Cut each roll in half and spread mayonnaise on each side of the roll. Fold a slice of ham in half, then in half again and place on the roll. Top with small slice of Havarti cheese. Place top of roll back on to form sandwich.
Place rolls close together in a 13x9 baking pan until pan in completely full. More than one batch will be needed to make all 24. I was able to fit 15 in the pan.
Whisk together all sauce ingredients and brush it generously over the tops of all the rolls. Let the rolls set until the butter has set up a bit.
For a toasted bun, bake uncovered. For softer rolls, cover pan with aluminum foil. Bake for 12-15 minutes.
Rolls can be made a day ahead and stored in fridge until ready to bake.
You may not use all of the sauce. I brushed on one layer, and then went through and added another for good measure. They were perfect!
While these fabulous little sliders are great for a party or game day, they are actually ideal for a quick hot lunch too!
You can prepare this recipe ahead, and even portion it down to 3 or 4 sliders, and then just pop them in the oven for fifteen minutes.
If you work outside the home, cook them up first then wrap them in foil. When lunchtime rolls around you can eat them as is or zap them in the microwave for a few seconds.
I am a Havarti NUT, but if you prefer other flavors try Swiss, Cheddar or Provolone cheese.
I prefer a softer bun, so I cover mine with foil the entire time. If you want them browned and a little crisp, do not cover with foil.
