Preparation Preheat oven to 350°F. Arrange bread slices in one layer on 2 baking sheets and sprinkle half with Parmesan. Toast slices in upper and lower thirds of oven until crisp and golden, 8 to 12 minutes, and cool. Crostini may be made 2 weeks ahead and kept in an airtight container at room temperature. In a colander or sieve drain tomatoes well, pressing gently on solids to squeeze out as much liquid as possible, and blot with paper towels. Chop tomatoes fine. In a bowl stir together tomatoes, oil, garlic paste, parsley, sugar, and salt and pepper to taste. Put a heaping teaspoon tomato mixture on each Parmesan crostino and top with 1/4 teaspoon olive paste. Spread each plain crostino with 1/2 teaspoon olive paste. Spread each plain crostino with 1/2 teaspoon olive paste and top with a heaping 1/2 teaspoon tomato mixture. Garnish crostini with parsley leaves.
