Start by placing your rice in a pot of water on the stove top to boil.
Heat a frying pan over medium/low heat while you chop your cauliflower and whisk all of the teriyaki sauce ingredients together in a bowl. Toss both the sauce and the cauliflower into the frying pan and occasionally stir for about 10 minutes until the sauce thickens and coats the cauliflower.
Meanwhile, you can prep the other ingredients by slicing the avocado and spring onion.
When everything is cooked you can assemble your bowl with the drained rice, sticky teriyaki cauliflower, avo and sauerkraut, then sprinkle the seeds and spring onions on top and serve.
