Marinade:
1/4 c. Olive oil
1/4 c. Worcestershire sauce
3 T. Purchased barbecue sauce
2 T. Balsamic vinegar
4 garlic cloves, smashed
2 sprigs of thyme (I didn’t use)

Beef:
4 6-8 oz. petite sirloin or beef fillets
4 cedar grilling planks, soaked

First
In a large zip top plastic bag combine marinade ingredients, add steaks and marinate at room temperature for 20 minutes.

Next
Preheat grill to high heat. Remove steaks from bag, discard marinade, and season both sides of steaks with salt and pepper. Sear steaks on grill for one minute per side, transfer steaks to plate and tent with foil.

Last
Reduce grill temperature to medium-low heat, about 350 degrees. Place planks on grill, close lid, and heat for 3 minutes. Using tongs, flip the planks and place steaks directly on heated sides of planks. Close lid and grill for 7-8 minutes for medium or until desired doneness. Remove planks and steaks from grill. Allow to rest for 5 minutes before serving.
