Heat the oven broiler. Place the bread slices on a large baking sheet. Brush both sides with olive oil. Toast lightly under the broiler, turning once (watch them, they will cook quickly!)
In a small bowl, combine the goat cheese, parsley, oregano, and 1 t oil from the jar of sun-dried tomatoes. Set aside.
In another small bowl, combine the tomatoes, olives, capers, salt, pepper, lemon zest, onion, and 1 T olive oil.
Take each toasted crostini and spread a thin layer of the goat cheese mixture. Top each with tapenade.
