Hazırlanışı
1Preheat the oven to 350°F. Place the walnuts on a rimmed baking sheet, and toast until lightly browned and fragrant, about 10 minutes. Set aside. When cool, chop the walnuts coarsely.
2Whisk together the eggs, cream, vanilla extract, cinnamon, nutmeg, and salt in a medium bowl, and set aside. Combine the bananas, dark brown sugar, and walnuts in another bowl; set aside. Lay out 6 slices of bread on the work surface. Top each slice with 1/3 cup banana mixture. Top with the remaining bread slices; press gently to seal the sandwiches.
3Place the sandwiches in a shallow baking dish (or 2 dishes) large enough to hold them in a single layer. Pour the egg mixture over the bread, and soak 10 minutes. Carefully turn the sandwiches over, and soak 10 minutes more, or until the bread is soaked through.
