In a small saucepan, combine half of the blueberries, the sugar, cornstarch, cinnamon, black pepper and 1/3 cup water. Over medium heat, bring to a boil: boil for 1 minute; remove from heat. Stir in remaining blueberries; cool. Toast waffles; place on dessert plates. Scoop frozen yogurt onto waffles; top with blueberry sauce.
