Preheat oven to 375° F.
Separate the crescent dough into 4 long rectangles.
Line your half sheet baking pan with parchment paper. Arrange the rectangular crescent dough on the baking pan and press the perforations to seal.
In a small mixing bowl, combine the softened butter and honey. Brush the mixture on the dough. Bake for 8 to 12 minutes or until lightly golden. Set aside to cool for 15 minutes.
Get another baking sheet and line it with parchment paper. If you don't have another baking pan, just wait for the dough to cook, transfer the dough on a cooling rack to cool, then line the baking sheet with fresh parchment paper.
Place one of the baked crescent rectangles on the baking sheet. Layer it with the turkey slices then add another crescent rectangle. Layer the ham and cheese then another crescent rectangle. Evenly spread the jam on the crust then place the last crescent crust on top. Brush with honey and sprinkle with sesame seeds.
Bake the loaf for another 10 to 15 minutes or until heated through and golden brown. You can also wrap it in plastic wrap and refrigerate for the next day. Sprinkle with powdered sugar after baking as desired.
