- 0.75-1 inch thick This is a hearty tasty combination of Caesar salad and steak all in one. Any tender cut of beef, or leftover pieces of filet can be used. Trim beef into strips 2 cm to 3 cm thick strips. Wash romaine leaves, shake and dry well and tear into bite-sized pieces. (May wrap in layers of paper towels, put in plastic bag and refrigerate to keep crisp.) Combine next 10 ingredients, whisking well to blend. Set aside. When ready to serve, bring steak to room temperature. Put greens in large salad bowl and add Parmesan cheese, blue cheese and croutons. Cook steak on hot grill, or pan-fry in heavy skillet on high heat approximately 4-5 minutes each side, for medium rare. Sprinkle with salt and pepper after turning once. Slice steak across grain in thin slices and add to salad. Pour on dressing and any meat juices, toss and serve immediately. Pass extra Parmesan cheese and a pepper mill.
