Preheat the oven to 350°F. Remove Hawaiian rolls from packaging, but keep the original box packaging. Slice the tops off the rolls and carefully set them aside until ready to use.
Lay the bottom halves of the rolls in the box the rolls came packaged in. Layer cheese slices on the rolls to cover rolls completely, overlapping the cheese as necessary.
Layer turkey sliders on top of the cheese. Fit one slice of turkey on each bun.
Carefully top with buns and seal the sides of the box.
In a small bowl, combine melted butter with Dijon mustard, Worcestershire sauce, poppy seeds, and dried minced onion.
Whisk to combine and pour on top of the buns. Use a pastry brush to spread the glaze evenly.
Wrap tightly in foil.
Bake in the oven preheated to 350°F for 15-20 minutes until the cheese is nicely melted and the sliders are warmed through. Unwrap the foil, serve, and enjoy!

Notes
You can make a smaller batch (as shown in my images) by halving the recipe.
Be sure to fit one slice of turkey on each bun, so once they are cooked they will pull apart easily without pulling the turkey off of another bun.
If you overlap the turkey to more than one bun you will have to cut through them after they are cooked to make sure they will pull apart easily.
If the butter sauce is too thick you can heat it in the microwave to thin it out a bit for pouring or you can brush it on.
