Peel kiwis and banana and cut into slices. Save a couple of kiwi slices for decoration.
Place kiwi and banana slices in a blender. Add greek yogurt and about 1/2 cup water (more as needed, if the smoothie is too thick). Blend until smooth.
In a glass jar, place a few kiwi slices on the glass wall and slightly push them onto the glass to create a good contact. Pour in the smoothie and top with blueberries, quinoa puffs and mint leaves. Serve.
