Add Greek yogurt to a mixing bowl and stir until smooth and creamy

Mix in lemon zest, vanilla extract, ground spice, and salt until fully combined and fragrant

Fold in the crushed blueberries, ensuring they are evenly distributed throughout the mixture

Line a tray with parchment paper and spoon small clusters of the mixture onto it

Shape into bite-sized rounds using the back of a spoon, keeping them slightly thick

Transfer the tray to the freezer and let the bites firm up until fully set and solid

Once frozen, remove and let sit briefly at room temperature before serving for a softer texture
