Rinse the blueberries thoroughly under cold running water and let them drain well in a colander. Pat them dry if needed with a clean piece of paper towel. Meanwhile, chop the walnuts with a chef's knife into coarse pieces so they retain their crunchy texture in the dish.
Take a breakfast bowl and spoon the full-fat curd cheese into it. Spread the curd cheese with the back of a spoon in an even layer over the bottom. Then sprinkle the dry blueberries and chopped walnuts in a generous layer over the curd cheese.
Finish the preparation by sprinkling the teaspoon of cinnamon over the bowl. Distribute the spice as evenly as possible over the curd cheese, nuts and berries to ensure plenty of flavor in every bite.
Serve the dish immediately after assembly. Eat the curd cheese while it is still well chilled, ideal as a quick start to the day or as a hearty snack.
