Grilled Steak
Rub steak all over with olive oil and season with salt and pepper to taste. Grill steak over a preheated grill, turning once until steak reaches your desired doneness (4 minutes for medium-rare, 5-6 minutes for medium)
Let steak rest 10 minutes then thinly slice against the grain. Toss balsamic dressing into salad then arrange steak on top of salad. Serve salad immediately and enjoy!
