Press the seams together to form one large piece of dough
Line or grease a 7 x 11 baking dish with parchment paper or nonstick spray
Lay the dough down in the baking dish and bake for the time required on the tube
Remove when cooking time is up
Spread the Dijon mustard over the top of the cooked croissant bread
Layer on 4 pieces of cheese or as much cheese as you would like to cover the surface of the bread
Fold each ham piece in half and layer on top of the cheese
Top the ham with the remaining slices of cheese
Remove the second batch of dough from the tube. Again, pinch the seams closed, and place on top of the cheese slices
In a small bowl, melt the butter, and add the parsley and garlic. Brush on top of the dough
Bake in the oven for 20 - 25 minutes or until the dough is golden brown on top, and the sandwiches are heated through and the cheese is nice and melty!
Remove from the oven and let rest for 5 minutes to cool slightly as the cheese will be VERY hot and can burn easily
