Step 1

In a small bowl, whisk together Worcestershire sauce, brown sugar, and Dijon mustard.

Step 2

Place the steak in a large zip-top plastic bag or shallow dish and pour marinade over top. Squeeze air out of the bag and seal to close or cover the dish. Gently toss to coat the beef in the marinade. Refrigerate for at least 30 minutes, or up to 24 hours.

Step 3

In a small bowl or measuring cup, whisk together balsamic vinegar, mayonnaise, water, brown sugar, garlic and mustard. While continually whisking, gradually stream in the olive oil until the ingredients are completely combined. Season with salt and pepper, to taste. Set aside while you prepare the remaining ingredients, or refrigerate in an airtight container or jar for up to 1 week.

Step 4

After at least 30 minutes in the refrigerator, remove the steak and discard the marinade. Wipe excess marinade off of the steak by patting it with paper towels. Season the meat on both sides with the garlic powder, salt and pepper. Allow to stand at room temperature for 20-30 minutes before grilling.

Step 5

Lightly brush or spray the steak with oil.

Step 6

Preheat your grill for high direct heat (about 450° F). Grill the steak covered for about 5 minutes. Turn and cook covered for about 3-4 more minutes, or until the meat reaches the desired level of doneness. Baste with the glaze during the final few minutes. Pull the steak off the grill at 120 to 125°F for rare, 130-140°F for medium rare, and 145°F for medium. Allow to rest for 10-15 minutes. Slice thinly against the grain and serve on top of salad.

Step 7

Place the lettuce on a large serving tray or on individual plates. Top with the tomatoes, red onion, cucumber, blue cheese and sliced steak. Drizzle with balsamic dressing. Garnish with crispy fried onions, if desired. Serve immediately.
