In a medium mixing bowl, combine the Greek yogurt, protein powder, and lemon juice.
Whisk the mixture vigorously until the protein powder is fully incorporated and the texture is smooth.
Gently fold in the lemon zest and half of the fresh blueberries.
Transfer the yogurt mixture into a serving bowl.
Top the bowl with the remaining blueberries, chia seeds, and granola.
Drizzle with honey or maple syrup if desired and serve immediately.
