In a large mixing bowl, whisk together the egg, mayonnaise, lemon juice, Old Bay, mustard, Worcestershire sauce, celery, chives, salt and pepper until well combined.
1 egg, ¼ cup mayonnaise, Juice of ½ lemon, 1 teaspoon Old Bay seasoning, 1 ½ teaspoons Dijon mustard, 2 teaspoons Worcestershire sauce, ½ teaspoon black pepper, 1 tablespoon fresh chives, 1 stalk fresh celery, 1 teaspoon kosher salt
Using a rubber spatula, gently fold in the crab meat and bread crumbs into the mayonnaise mixture. Mix until just combined so as not to break down the crab meat too much. Form into 4 equal sized patties and chill for 15 to 20 minutes in the refrigerator.

In a small mixing bowl, whisk together ingredients for the spicy mayo until well combined. Set aside.

In a large skillet, add the olive oil over medium high heat. Once the oil is hot and begins to shimmer, add the crab cakes to the pan. Saute until golden brown, about 4 to 5 minutes per side. Remove the pan from the heat.
2 tablespoons olive oil
Spread 1 to 2 tablespoons of the spicy mayo on each side of the toasted brioche buns. Add the crab cakes, lettuce and tomato. Top with the other half of the bun, then serve.
