- Stir together tartar sauce, 2 tablespoons green onions, 2 teaspoons thyme, and capers in small bowl.
- Place white bread in food processor; using on/off turns, process until very coarse crumbs form. Transfer breadcrumbs to large bowl. Using on/off turns, finely chop celery; add to bowl with breadcrumbs. Using on/off turns, coarsely puree fish; add to bowl. Add remaining 1/2 cup chopped green onions, 1 1/2 tablespoons chopped fresh thyme, egg, salt, and ground black pepper to bowl. Mix gently but thoroughly.

Divide fish cakes among 4 plates and garnish with tartar sauce and lemon wedges.
