This crab bruschetta recipe is courtesy of John Sierp.
In a medium bowl, stir together tomatoes, onion, garlic oil, parsley, basil, salt, and pepper. Refrigerate, covered, for at least 2 hours.
Preheat oven to 375 degrees. Lay bread slices in a single layer on a baking sheet; brush with olive oil. Bake until golden brown.
Spoon 1 tablespoon of tomato mixture onto bread; top with a piece of crab. Repeat with remaining bread slices. Season with Old Bay; serve immediately.
