Heat your oven to 350°F and spray a 9x13 inch baking dish really well with cooking spray. Put it aside for now.

Open up your crescent roll package and spread the dough flat on a cutting board. Press any open seams together and stretch it to about 10x13 inches.
03 -
Cover the dough with ham slices but leave about half an inch around all edges bare. Then add your Swiss cheese on top, followed by the American cheese.

Starting with the short edge, roll everything up tightly. Grab a serrated knife and cut into 16 equal pieces. An easy way is to cut in half, then cut each half in half, and so on.
05 -
Put all your cut slices into the greased baking dish. Leave them there while you make the sauce.
06 -
Melt your butter in a microwave-safe bowl. Stir in the mustard, poppy seeds, garlic powder, Worcestershire and salt until everything's mixed well.
07 -
Brush or pour the butter mix all over the tops of your slices, making sure they're all covered.
08 -
Put the dish in the oven uncovered and bake for 20-24 minutes until they're slightly brown on top and the dough has risen.

Take them out and let them sit for a few minutes before serving. Sprinkle with parsley if you're feeling fancy.
