Rosemary Dijon Pork Tenderloins

1/3 cup Dijon mustard
2 tablespoons freshly ground black pepper
1 tablespoon freshly chopped rosemary leaves, plus 4 sprigs rosemary, with hard woody stems
5 large garlic cloves, 2 cloves minced, 3 cloves smashed
2 pork tenderloins, about 1-pound each

In a small bowl, whisk together the Dijon mustard, fresh ground black pepper, chopped rosemary, and minced garlic and mix well. Rub the mustard mixture over the surface of the tenderloins and wrap in plastic wrap. Marinate in the refrigerator for 1 hour.

Preheat oven to 375 degrees F.

Bake on roasting pan according to package directions. I use a thermometer to know for sure since pork is generally pinkish in the center anyway.
