This is a master piece. I don't know how many times I have made this combination, but this is certainly the best-looking one I have ever done. I watched Ina Garten make this on more than one occasion and I had to try it. I then forgot about it and drew on it once or twice a year and now today, ahhh. I have a happy family today. Along with the greatest weather, this has been a scrumptious day all around. This is two sheets of puff pastry with layers of ham and cheese on top of the mustard slathered bottom and a homemade sauce on the top layer. The cheese is Pepper Jack and also baby swiss. The ham is thin slices of deli ham. Ina used this as a party starter, but I use it as lunch or dinner. It cannot be more simple to prepare and you will get rave reviews even if you have to rave yourself. (I do that on occasion.)
Slice into squares and enjoy.
