Preheat oven to 400 degrees F. Spray a baking sheet with nonstick cooking spray. Place blueberries on baking sheet and drizzle with maple syrup. Toss until blueberries are coated. Place the sheet in the oven and roast for 8 minutes or until blueberries are juicy and ready to pop.
While the blueberries are roasting, make the oatmeal according to package (I used milk instead of water). Combine milk and oats in a medium saucepan; bring to a boil over medium-high heat, stirring often to prevent boiling over. Cook until thickened; divide oatmeal between two serving bowls. Top with maple roasted blueberries, almonds, and chia seeds. Drizzle with additional maple syrup, if desired. Serve immediately.
