Pre-heat oven to 350°F.
Take tenderloins out of package.
Rinse and pat dry.
Spray a 9 × 13-inch baking dish and place tenderloins inside.
Use a paring knife and poke holes on the top side of the tenderloins, about an inch deep.
Place a garlic piece into each hole.
Make the marinade next:
a) In a measuring cup or bowl, whisk together everything except for olive oil.
b) Then slowly drizzle in the oil.
While whisking, pour marinade juices over tenderloin and roast in oven for 45 to 50 minutes or until cooked thoroughly through.
Allow meat to rest about 10 minutes before cutting into 2-inch serving pieces.
