To make the dry rub combine all ingredients together in a bowl. Mix well then rub all over the London Broil. Refrigerate for 2-4 hours.
When ready to make the salad heat a grill to high heat. Place the London Broil on the grill and cook on one side for 3 minutes. Flip it over and cook until the internal temperature reaches 135. Remove to a cutting board and rest for 5 minutes before slicing.
Meanwhile, place the romaine lettuce in a large bowl. Top with all of the other ingredients then toss to combine.
Divide the salad mixture between 4 plates and top with grilled steak.
