Roast Pork with Mustard Sauce

We decided to make this for our European tour themed progressive dinner on Saturday. So I wanted a practice run just to prepare for the big day and it is Thursday. It is really an outstanding dinner and not too hard to make, but is really decadent, so it can't be an every day dinner.
