Instructions Set aside 1 cup swiss for top. Spread 12 bread slices with mustard; layer each with ham and 1/4 cup swiss. Spread cherry preserves on remaining bread. Top swiss with bread slices preserves side down. Cut each sandwich diagonally into four triangles. Arrange sandwiches crusts up in a greased 3-quart or 13 x 9-inch baking dish. Whisk the eggs, milk, garlic powder, salt and pepper in a large bowl. Pour egg mixture over sandwiches. Sprinkle with reserved swiss. Cover and refrigerate overnight. Remove strata from the refrigerator 30 minutes before baking. Heat oven to 350°F. Bake, covered, for 45 minutes. Uncover; bake for 15 minutes longer or until a knife inserted near the center comes out clean and thermometer inserted in egg mixture reads 160°F. Let stand for 10 minutes. Serve with maple syrup.
