Preheat oven to 325°.
Combine first 6 ingredients in a large bowl. Combine the juices in a small saucepan. Bring to a boil; cook until reduced to 2/3 cup. Remove from heat; stir in honey. Slowly pour juice mixture over oat mixture, tossing to coat. Spread oat mixture evenly onto a jelly roll pan coated with cooking spray. Bake at 325° for 40 minutes or until golden, stirring occasionally. Cool slightly; stir in blueberries. Cool completely, and store in an airtight container.
