In a blender or food processor, combine the tofu, self-raising flour, olive oil, tamari, salt, garlic powder and water.
Add one of the following, depending on your variation:
For plain, add nothing else.
For beetroot, add 1½ tsp beetroot powder or 1 cooked beetroot.
For spinach, add 30g fresh spinach leaves.
Blend until smooth. The batter should resemble a slightly runny pancake mix – not too thick or watery.
