Preheat the oven to 350 F.

In a small saucepan, melt the butter. Then, stir in 1 tablespoon dijon mustard and 1/2 tablespoon maple syrup. Set aside.

In a small bowl, combine the remaining 2 tablespoons Dijon mustard, 1 1/2 tablespoon maple syrup, and mayo.

Take the rolls out of the packaging without breaking off any individual rolls. Then, slice them in half so that you have one whole top piece and one whole bottom piece.

Lay the bottom half flat in a baking pan, then spread on the Dijon-maple-mayo sauce. Top with the sliced ham, then the sliced turkey, then the swiss. Top with the top layer of rolls, then brush on the butter—make sure to use it all up!

Cover and bake for 20 minutes, then uncover and bake for another 5 minutes until crispy.

Remove from the oven and serve warm.
