In large saucepan, bring water and orange juice to a boil. Stir in 2 cups oats. Cook uncovered over medium heat, 1 minute for Quick Oats, 5 minutes for Old Fashioned Oats, stirring occasionally. For sauce, in small saucepan, bring orange juice to a boil. Stir in cranberries and agave nectar. Reduce heat to low; simmer 5 to 7 minutes or just until thickened and berries begin to pop. Top each serving of oatmeal with about 1/4 cup sauce and garnish with shredded orange peel, if desired.
