Place the frozen blueberries in a small non-stick skillet or saucepan over medium heat.
Sauté the blueberries for 4 to 5 minutes, stirring occasionally, until they burst and the juices thicken into a warm, jammy syrup.
If using maple syrup or cinnamon, stir them into the blueberry mixture during the final minute of cooking.
Transfer the cold cottage cheese into a serving bowl, spreading it slightly to create a shallow well in the center.
Pour the hot blueberry compote directly over the chilled cottage cheese.
Top immediately with slivered almonds and serve to enjoy the contrast between the cold cheese and warm fruit.
