One of the favorites I usually make for the holidays. I recently found the trick to this one though: Marinate it overnight in the refrigerator. All the great flavors seep into the meat. So tasty and very quick and easy!
1/2 cup of coarse ground mustard
3 TBSP balsamic vinegar
8 cloves garlic, minced
3 TBSP olive oil
1 pork loin 2-3lbs
Mix the first four ingredients together and smear over the pork loin in a casserole dish. Cover with saran wrap and place in refrigerator overnight. Bake at 350 degees for 2 hours. Slice and serve!
