2 egg whites, lightly beaten
Combine egg whites, mayonnaise, parsley, Creole seasoning, Worcestershire sauce, pepper, and dry mustard. Gently stir in the bread crumbs and crabmeat. Shape mixture into 8 patties, about 2 1/2 inches in diameter. Place patties on a baking sheet lined with waxed paper or non-stick foil; cover and chill for 30 to 60 minutes.
Spray a large nonstick skillet with vegetable cooking spray or use a little olive oil to coat the bottom. Place over medium-high heat. When the skillet is hot, add crab cakes; cook for 3 to 4 minutes on each side, or until browned.
