Preheat a grill to high heat. Rub the flank steak with olive oil and season with salt and pepper. Cook the steak to the desired doneness. We recommend cooking the steak to medium, or about 5 minutes per side. Remove the steak from the grill and let rest for 5 minutes.
While the steak is resting, combine the romaine, arugula, and spinach in a large bowl and toss well. Divide between serving bowls. Top the lettuce with the cucumber and tomatoes.
Slice the steak into strips and lay over the lettuce. Drizzle the cilantro dressing over top. Serve and enjoy!
