Heat 2 teaspoons olive oil in a large nonstick skillet over medium-high heat. Add the scallions and bell pepper and cook until they begin to soften, about 2 minutes. Cool slightly. Mix 1/2 cup panko, the egg and milk in a small bowl. In a medium bowl, whisk the Worcestershire sauce, mustard, lemon juice, Old Bay and hot sauce; fold in the crabmeat, panko mixture, scallionbell pepper mixture, 1/4 teaspoon salt and a pinch of pepper. Shape into 8 patties and refrigerate 30 minutes. Coat the crab cakes with the remaining 1/2 cup panko. Heat the remaining 1 tablespoon olive oil in the skillet over medium-high heat. Mist the crab cakes with cooking spray and cook, sprayed-side down, 3 to 4 minutes. Spray the tops, flip and cook 3 to 4 more minutes. Serve with lemon wedges.
