In a medium bowl, add the crab, panko, egg, mayonnaise, dijon, Worcestershire, Old Bay and salt and mix lightly to combine. Form 4 cakes and set aside.
Heat a medium saute pan to medium-high, spray with cooking spray and add the crab cakes. Fry until golden brown on each side, about 10 minutes total. Allow to cool for 5 minutes before serving.
In a small canning jar add the shallot, sugar, mustard, salt, red wine vinegar and canola and shake well to combine.
In a large bowl add the lettuce and toss with the vinaigrette to coat. Arrange lettuces on 2 large serving plates. Place the hard boiled eggs, tomatoes and avocado around and top with the crab cakes.
