Heat a small piece of butter in a small non-stick pan over medium heat. Add the oatmeal and sweet lupine meal, and fry for 2-3 minutes until the oatmeal is golden brown.
Add the blueberries and cinnamon sugar. Fry for 2-3 minutes until the blueberries soften and release their juice.
Pour the chilled yogurt into a deep bowl. Top with the warm blueberry mixture and serve immediately.
