In a shallow bowl beat together eggs, milk, granulated sugar, 1-1/2 teaspoons of the orange peel, vanilla, and cinnamon with a whisk. Dip bread slices into egg mixture, coating both sides.
In a skillet or on a griddle melt 1 tablespoon of the butter over medium heat; add half of the bread slices. Sprinkle some of the granola on top of each slice of bread in the skillet, pressing in gently with spatula so granola sticks. Flip each slice, pressing lightly with the spatula. Cook for 2 minutes more or until golden brown. When removing from pan, flip each slice so granola side is on top.
Repeat with remaining butter, bread slices, and granola. Serve with Cinnamon-Yogurt Sauce, remaining orange peel, and syrup. Sprinkle with powdered sugar. Makes 4 servings.
