How to Make It
Preheat oven to 400°.
Place bread slices on a large baking sheet. Bake at 400° for 10 minutes or until crisp. Cool slightly. Lightly rub 1 side of each bread slice with cut sides of garlic. Discard garlic.
Combine onion, celery, bell pepper, and crab in a bowl. Combine parsley and remaining ingredients. Spoon over crab mixture, and toss gently. Top each bread slice with 1 tablespoon of crab mixture.
