How to Make It
Preheat oven to 400°F. Place ciabatta halves on a small baking sheet. Spread bottom half with hot pepper jelly. Place turkey, apple, and brie on top of jelly. Bake in preheated oven until brie melts and top half of roll is light golden brown, about 3 minutes. Remove from oven and place arugula on top of brie. Brush top half of roll with mustard and place on top of arugula to make a sandwich. Serve hot or at room temperature.
