Preheat oven to 400ºF. Spray a large baking sheet with cooking spray.

In a medium bowl beat eggs, peel, juice, 2 tablespoons of the sugar and the salt until well blended. Pour into a 13 × 9 × 2-inch baking pan; set aside. In a small bowl combine blueberries and the remaining 1 tablespoon sugar; set aside. With the tip of a sharp knife, cut a 1-1/2-inch wide pocket in the side of each bread slice. Fill pockets with reserved blueberry mixture, dividing evenly. Place filled slices in egg mixture. Let stand, turning once, until egg mixture is absorbed, about 5 minutes on each side. Arrange bread on prepared baking sheet; sprinkle with almonds. Bake until golden brown, about 15 minutes, turning slices after 10 minutes. Serve with Blueberry Orange Sauce. Serves 4 to 6 portions
