Carefully pit the dates if they are not already pitted, making a small slit in each one.
In a mortar and pestle, grind together the walnuts, pine nuts, and freshly ground black pepper until you achieve a coarse, slightly chunky mixture.
Stuff each date with a small amount of the walnut-pine nut mixture, pressing gently to fill them completely.
In a small saucepan, heat the honey over medium heat until it becomes more fluid and warm but not boiling.
Once the honey is heated, remove it from the heat and carefully baste each stuffed date with the warm honey, coating them evenly.
Let the dates sit for a few minutes to absorb the honey and cool slightly.
Serve the dates warm or at room temperature.
