As long as they like pork, this is one of my favorites. Put it in a nice serving dish and it looks great:
Roast Herbed Pork Loin [Note: I use a one or two lb tenderloin from Hormel when I cook for 4 - cooks very fast, and you just halve the recipe below]
5-6lb Pork Tenderloin
3 crushed bay leaves
Kitchen bouquet [I skip this step]
4 Tbsp Dijon Mustard
1 Stick butter
3 Tsp Thyme
2 Cloves Garlic
Mix butter, thyme, bay leaves and mustard. Rub kitchen bouquet over rust. Next, rub mustard mixture over entire roast. Preheat oven to 350 degrees, bake uncovered about 2-3 hours. Baste twice while cooking.
This gives you super tender pork with a yummy, not too strong mustard glaze on the outside. Goes well with braised baby potatoes, gratin or similar. Roasted asparagus [olive oil, season to taste, broil for 8 - 10 minutes] would be awesome with this as well.
Good luck!
