Add all of the dried ingredients to a mixing bowl and whisk to ensure they are well combined.
Stir together the bouillon and olive oil in a jug before slowly pouring into the dried ingredients. Mix well as you add the liquid.
Once the liquid has been added to the dried ingredients you should have a stretchy, sticky dough ball. Knead the dough ball on a lightly floured surface for a few minutes so that it is one scraggy dough ball.
Cut the dough into 8 pieces and shape them into ovals or chicken breast shapes. The shape doesn't matter too much but you want them to be similar sizes so that they cook evenly.
Bring a large pan of water to the boil and place the dough into the steaming basket (you may need to do this in batches). Cover with a lid and steam for 30 minutes.
You will know they are done as they will have puffed up and be firm to the touch.
(If you do not want to use all the "chicken" straight away, follow the storage instructions below).
To shred the seitan into chicken strips, take two forms and pull the seitan apart. Keep doing this until you have the desired texture.
Place a frying pan over a medium heat and dry fry the seitan to create some crispy edges and to ensure it's piping hot before serving!
Notes
Storage instructions
This seitan keeps best if you store it whole (i.e. not shredded). If you don't want to use all of the seitan at once, place it in an airtight container and store in the fridge for up to a week.You can store the shredded seitan in the same way but it may dry out a little quicker. Add a little water or stock when you reheat it to add some extra moisture.
