Northern Sweet Mesquite Grilling Planks: Beef cutlets, beef medallions, and beef steak has never tasted better than grilled on a rectangle or oval sweet mesquite plank. It is so easy. Soak your plank in water or merlot for two hours. Season your entrée as usual and place on the plank on a cookie sheet. Put cookie sheet directly under your oven broiler element or on your grill. Grill approximately 10 minutes. Then flip the entrée until done to taste. Add garnish and serve on the plank!
