Put the tofu cubes in a bag or bowl and coat in hoisin sauce. Set aside in the fridge to marinate for at least 30 mins or longer if you can.

Prepare the veg by chopping the onion, garlic and chilli. Then finely slice or chop the remaining veg.

Heat a tbsp of oil in a wok over a medium / high heat and add the tofu and remaining marinade. Cook for 3-4 minutes until the tofu starts to brown. Then transfer the cooked tofu to a bowl/plate

Heat another tbsp of oil in the wok over a medium heat. Add the onion and fry for a minute. Then add the garlic and chilli and fry for another minute.
