To make this vegan , add nut milks/ coconut milk or coconut yoghurt!I used greek yoghurt and water as liquid base to get the consistency, but if you are a vegan, you can replace greek yoghurt with coconut yoghurt and it will just be perfect!
To make it more rich and creamy -
Add 1/2 and avocado
Add a frozen banana if you want it more sweet and creamy.
