Preheat oven to 350°F. Spray bottom and side of a 9-inch pie plate with vegetable cooking spray; sprinkle with graham cracker crumbs, and tilt to coat evenly. Place a coffee filter or two layers of paper towels in a strainer; stir 1 container of the yogurt and spoon it into the filter; set aside to drain, stirring occasionally, about 30 minutes. Meanwhile, in a food processor, blend the remaining container of yogurt, cottage cheese, cream cheese and cornstarch until smooth. Add the eggs and pulse until combined. Carefully pour into the crumb-coated pie plate; smooth top. Bake until set in the center, about 30 minutes. Meanwhile, prepare the Blueberry Sauce. When pie is set, spread the drained yogurt over the top; bake 5 minutes longer. Cool to room temperature on a wire rack. Chill until cold. Serve with Blueberry Sauce
