Thinly slice a baguette-style French bread loaf for these bruschetta (broo-SHEH-tah) appetizers. Toast the bread slices and top with a mixture of crabmeat, shrimp, and tomatoes tossed in a lemony herb and garlic sauce.
Stir together the 1 tablespoon olive oil, lemon juice, chives, basil, mint, and garlic in a mixing bowl. Add crabmeat, shrimp, tomatoes, and onion; toss to coat. Cut the bread into 48 thin slices; brush one side of each slice with some of the 2 tablespoons olive oil; sprinkle lightly with pepper.
Arrange bread slices, oiled sides up, on baking sheet. Broil 3 to 4 inches from heat for 1 to 2 minutes till toasted. Turn and broil other side till toasted. Arrange on a serving platter with oiled sides up; spoon seafood mixture on each slice. Garnish with fresh basil, if desired. Serve at once. Makes 48 appetizer servings.
