Mix the marinade ingredients together into a small bowl or plastic tub with a lid.
Cut the tofu into 8 equal slices then place them in the marinade. Turn them over to make sure both sides are coated.
Leave to marinade for at least an hour if possible, turning from time to time.
When you're ready, either pre-heat the oven to 180ºC and place the slices on a non-stick baking tray and bake for 20 minutes, turning them over after 10 minutes.
Or place the slices in a quality non-stick frying pan over a medium heat (no oil needed) and 'fry' for 2 minutes. Turn over and 'fry' the other side until lightly browned.
Use straight away whilst hot or leave to cool and keep in a container in the fridge until ready.
