In a small bowl, combine the fresh blueberries, lemon juice, and lemon zest. Gently mash the blueberries with a fork to release some juices, then set aside to marinate for about 10 minutes.
While the blueberries are marinating, preheat your oven to 400°F. Place the slices of bread on a baking sheet and brush each side lightly with olive oil.
Toast the bread in the oven for about 5-7 minutes, flipping halfway through, until golden brown and crispy.
In a separate bowl, mix the ricotta cheese with 2 tablespoons of honey and a pinch of salt until smooth and creamy.
Once the bread is toasted, spread a generous layer of the ricotta mixture on each slice.
Top the ricotta with the marinated blueberries, ensuring an even distribution.
Drizzle a little extra honey over the top for added sweetness, and garnish with fresh mint leaves if desired.
Serve immediately and enjoy your delicious toast!
