Pork Tenderloin With Mustard Sauce

READY IN: 1hr 15mins
Recipe by DrGaellon

Adapted from a recipe by THERRELLFAMILY at allrecipes.com. The note there reads, "A wonderful overnight marinade makes the pork so flavorful - serve with the delicious, creamy mustard sauce. A super dish for buffets and potlucks, as it doesn't need to be piping hot. I never cease to get many recipe requests for this one!"

The marinade for the pork is so yummy. But I really didn't like the mustard sauce. I guess there was too much mustard powder for my taste. Thanks DrGaellon. Made for Bargain Basement tag game
