Strawberry Balsamic Mascarpone Bites 

In a small saucepan, bring vinegar to a boil over medium heat. Reduce heat, and simmer until vinegar is reduced by half, about 15 minutes. Transfer to a heatproof bowl, and let cool completely.

Preheat oven to 400°. Line 2 rimmed baking sheets with parchment paper.

Using a serrated knife in a gentle sawing motion, cut baguette into ⅛-inch-thick slices. Place on prepared pans, and drizzle with oil.

Bake until crisp, about 15 minutes. Let cool slightly.

In a small bowl, stir together mascarpone and pepper. Spread mascarpone mixture onto crostini. Top with strawberries, and drizzle with balsamic reduction. Serve immediately.
