Carefully chop the onions, mushrooms and capsicum.
Fry the onions in the oil for a few minutes before adding the mushrooms and capsicum.
Dry the tofu with paper towels, removing as much of the excess water as possible, before roughly mashing with a fork (leaving some bigger chunks).
Add the tofu, spices and nutritional yeast to the frying pan.
Cook until the tofu begins to brown.
Serve on toast with some fresh parsley.
Note: Nutritional yeast can be used as a replacement for cheese. It has a delicious, savoury flavour and is a good source of B vitamins, including B12!
