Preheat your oven to 350°F (175°C).
In a mixing bowl, combine the ricotta cheese, chopped pistachios, honey, vanilla extract, and sea salt. Mix until well combined.
Carefully open each pitted date and stuff it with about 1 tablespoon of the ricotta mixture. Press the sides gently to close the date around the filling.
Place the stuffed dates on a baking sheet lined with parchment paper.
Bake in the preheated oven for 10-12 minutes, or until the dates are warm and slightly caramelized.
Remove from the oven and let cool for a few minutes. Drizzle with additional honey if desired and garnish with fresh mint leaves.
Serve warm or at room temperature.
