In a mixing bowl, combine the softened cream cheese, Greek yogurt, powdered sugar, lemon juice, and lemon zest. Use an electric mixer to blend the ingredients until smooth and creamy.
In a large serving bowl, layer half of the mixed berries on the bottom.
Spoon half of the creamy cheesecake mixture over the berries, spreading it evenly.
Repeat the layers with the remaining berries and cheesecake mixture.
Top the final layer with granola evenly distributed for a delightful crunch.
Chill the salad in the refrigerator for at least 30 minutes to let the flavors meld together.
Before serving, garnish with fresh mint leaves for an extra touch of color and flavor.
