1. Cook the blintzes according to package directions.
2. With a fork, mix yogurt, peanut butter, milk, and cinnamon together until it achieves a smooth consistency. Start with one tablespoon of the milk and add more to adjust the thickness of the sauce to your taste.
3. Slice each blintz into three. Place all blintz rings on a platter. Drizzle the sauce over it and top with granola (recipe follows). You can certainly use store-bought granola, but homemade is always more fun!
