In a medium bowl, mix Greek yogurt and vanilla extract until well combined.
In serving glasses or bowls, layer half of the yogurt mixture at the bottom.
Add a layer of fresh berries on top of the yogurt.
Sprinkle a layer of mixed nuts over the berries for a satisfying crunch.
Drizzle a tablespoon of honey over the nuts for sweetness.
Repeat the layers, starting with the remaining yogurt, berries, and nuts.
Top with granola if using, and finish with another drizzle of honey.
Serve immediately and enjoy the harmony of flavors and textures!
