With a wire whisk, beat together eggs, orange juice, milk, sugar, nutmeg and vanilla. Place bread in single layer to fit tightly in a 9x13 inch casserole dish. Pour milk mixture over bread. Cover and refrigerate overnight, turning once.
Preheat oven to 400 degrees. Pour melted butter into a different 9x13 inch casserole dish. Spread butter evenly. Arrange soaked bread in a single layer in the casserole dish. Sprinkle with pecan pieces. Bake until golden brown, about 20-25 minutes. When removed from oven, sprinkle with hint of confectioners' sugar for presentation. Garnish with orange slices and fresh mint. Serve with warm maple syrup or fresh fruit. Makes 4 servings.
