Wash and prepare the mixed berries by slicing any larger berries (such as strawberries) into bite-sized pieces. In a glass or parfait dish, start by layering a spoonful of Greek yogurt at the bottom.
Add a layer of mixed berries on top of the yogurt. Sprinkle a tablespoon of granola over the berries.
Repeat the layers until you have used all the ingredients or reached your desired height.
Drizzle a little honey or maple syrup on top if you'd like a touch of extra sweetness.
Garnish with fresh mint leaves for added freshness and presentation.
Serve the mixed berry parfait immediately or refrigerate for a short time to allow the flavors to meld together.
