Mix the ingredients above in a deep dish and marinate tenderloin(s) for few hours or overnight. *A plastic zip bag also works well*
Preheat oven to 400 degrees F
Remove tenderloins from the refrigerator and let stand at room temperature for 15 minutes before roasting.
Grill or sear meat on high for about 6-7 minutes on each side and then transfer to a roasting pan.
Put roasting pan in the oven to continue cooking for another 20 minutes (or until cooked through).
Remove from oven when done, let stand a few minutes and slice.
Notes
ALTERNATIVELY: Place pork in a roasting pan with a 1/4 cup of chicken stock and cover with foil. Place in a 400 degree F oven and cook covered for 45 minutes and then uncovered for another 15-20 mins or until done.
