Ingredients
  

  • ½ cup mayonnaise
  • 1 tsp Dijon mustard
  • 1 tsp Worcestershire sauce
  • couple pinches kosher salt
  • ½ tsp garlic powder
  • 2 pkgs Hawaiian original sweet rolls 12 rolls each
  • 1 lb shaved rare roast beef deli meat
  • 1 small green bell pepper seeded, ribs removed, and sliced thin
  • ½ white onion sliced thin
  • couple pinches fresh cracked pepper
  • 12 slices white American cheese
  • 12 slices provolone
  • 1 stick unsalted butter melted

Instructions
 

  • Set up the Big Green Egg or grill to grill by indirect heat. Heat to a steady 350°F.
  • In a small bowl, combine the mayonnaise, Dijon, Worcestershire sauce, salt, and garlic powder.
  • Assemble the sliders: use a large serrated knife to cut the rolls into a bottom layer and top layer. Lay a bottom layer on a double layer of large pieces of foil. Spread half the Dijon-mayonnaise over, and layer half each the roast beef, bell pepper, onion, pepper, white American cheese, and provolone cheese. Finish with the top layer of bread. Brush the tops and sides with half the butter.
  • Repeat this process with the remaining ingredients. Pour any remaining butter over all the tops to use it all up (this is why it is important to assemble on foil for easier wrapping).
  • Wrap each prepared batch of sliders in the foil, taking care around the bottom to fold the foil up to hold the butter. Put to grill 10 minutes at 350°F.
  • After 10 minutes, open foil up and bake and additional 15-20 minutes more until sliders are thoroughly heated through and edges are toasty.

Notes

Sliders can be assembled and wrapped in foil hours in advance. It is preferable to allow some time for the bread to soak up the butter prior to cooking.
