Lemon zest

1. Preheat the oven to 180°C/350°F.
2. Brush the olive oil onto both sides of the bread. Set remaining oil aside.
3. Mash half the beans in a bowl. Add the remaining oil and lemon juice into the bowl, and mix. Add the tomatoes, onions, garlic, parsley, and parmesan to the bowl. Mix to combine.
4. Preheat a large pan over medium heat.
5. Place the baguette slices into the pan, turning once the bread is golden brown, about 1 minute.
6. Place the slices on a parchment-lined baking sheet. Top each slice with 1/4 cup of the bean mixture. Sprinkle each slice with a little extra parmesan.
7. Bake until the top is golden brown, about 10 minutes.
8. Remove the bruschetta from the oven, and garnish each with chopped parsley and lemon zest.
