Drain and flake crabmeat, removing any bits of shell.
Stir together crabmeat and next 7 ingredients. Shape into 6 (3 1/2-inch) patties. Chill 1 hour.
Cook patties in a nonstick skillet coated with cooking spray over medium-high heat 5 minutes on each side or until lightly browned. Place lettuce on muffin halves. Top with crab burgers; spoon Roasted Red Pepper Sauce over burgers. Garnish, if desired; serve with tomato wedges.
