Dijon Mustard Potatoes - Seriously Delish!

Who doesn't love the old "German" standby flavors of using mustards to jazz up a dish.  Last night I roasted a chuck roast for our Sunday dinner but wanted to do our potatoes other than mashed.  So simple.  I put 6 whole potatoes into the microwave for 12 minutes (of course this will vary depending on your microwave and prick the potatoes with a fork prior so they don't explode).  Once they were cooked and cooled a bit, I cut them all into quarters, put them in a casserole dish, and poured the following over the potatoes:  1 cup of Dijon mustard, 1/4 cup of yellow mustard, 1/4 cup of apple cider vinegar, 2 tbsp. of olive oil, 2 tbsp. of drained capers, 2 packets of Splenda (or you could use sugar in which case add 1 tbsp.) Mix up and pour over the potatoes, making sure they are all covered.  Put in the oven at 350 degrees for about 15 minutes and my goodness, you've got yourself some fabulous potatoes - and the sauce is equally fine on your roast.  Serve a nice salad along side and you've got yourself a nice Spring Sunday roast suppa....
