Preheat oven to 375℉.
On a lined sheet pan, roll out one of the crescent roll sheets and bake for 7 minutes.
While baking, mix together the sauce for the sandwiches. After the sheet has baked remove it from the oven, smear the sauce on the bottom and add the first layer of cheese. After, add the ham down by folding the slices like in the photo. Top with the last layer of cheese then place the final dough sheet on top.
Brush the dough sheet with the garlic herb butter then place in the oven for 20 minutes. When the ham and cheese crescent rolls are golden, pull them from the oven and garnish with grated parmesan.
Allow to cool for 5 minutes, serve and enjoy!
