Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper.
In a bowl, toss the sliced strawberries with honey and balsamic vinegar. Spread them evenly on the prepared baking sheet.
Roast the strawberries in the oven for 15-20 minutes, or until they are soft and caramelized. Remove from the oven and let cool slightly.
In a separate bowl, combine the ricotta cheese, powdered sugar, and vanilla extract. Use a hand mixer or whisk to whip until smooth and creamy.
While the strawberries are cooling, brush both sides of the bread slices with olive oil. Toast them in a skillet over medium heat or in a toaster until golden brown and crispy.
Spread a generous layer of whipped ricotta on each slice of toasted bread. Top with the roasted strawberries.
Garnish with fresh mint leaves if desired. Serve immediately.
