Heat oven to 425 degrees. Lightly butter and flour an 8-inch square pan, or coat lightly with nonstick cooking spray.

In a mixing bowl, stir together the cereal, flour, baking powder, salt, sugar and cinnamon. While stirring, slightly crush the cereal using the back of the spoon or rubber scraper; set aside.

In another bowl, beat eggs until well blended. Add milk, melted butter and vanilla, and mix well. Combine egg mixture with flour mixture. Pour batter (it will be thin) into prepared baking pan. Bake for 18-20 minutes or until it is set when lightly touched in the middle. Remove from oven and set on wire rack to cool for 10 minutes.

To serve, cut into 6 equal-sized bars and place on serving plates. Top each square with a dollop of Greek yogurt, surround with fruit, and drizzle with honey. Sprinkle with nutmeg or cinnamon and serve immediately.
