Preheat oven to 375 degrees F.
Clean strawberries and remove tops. Cut large strawberries into quarters and small strawberries in half.
In a medium bowl, whisk together honey, balsamic vinegar, and black pepper (if using). Add strawberries and toss to combine. Pour onto a parchment-lined, rimmed baking sheet, or into a baking dish.
Roast for 12 to 15 minutes, until strawberries are tender but still retain their shape. Remove from oven and transfer strawberries and pooled syrup to a bowl to cool slightly.
Place Brie in a clean baking dish or on a second parchment-lined baking sheet. Bake for 10 to 15 minutes, until cheese is soft and warm, but not melting out of the rind.
While Brie is baking, fold mint and pistachios into the strawberries. Top warm Brie with roasted strawberry mixture. Serve with assorted crackers, crostini, or sliced baguette.
