Chop the sugar snaps in half and finely slice the pak choi, as well as the coriander leaves, and add to the pan as well as 150ml of water. Stir through and bring to a boil. Taste and adjust the seasoning to your liking by adding more salt, tamari, lemon juice or chilli.
For the tempeh, in a separate frying pan put on high heat, once hot add 1 tbsp of oil and slice the tempeh into a rectangular piece approx 1 cm thick and add to the pan.
