Peel and crush the garlic, then peel and roughly chop the ginger. Trim the greens, finely shredding the cabbage, if using. Trim and finely slice the spring onions and chilli. Pick the herbs.

Bash the lemongrass on a chopping board with a rolling pin until it breaks open, then add to a large saucepan along with the garlic, ginger and star anise.

Place the pan over a high heat, then pour in the vegetable stock. Bring it just to the boil, then turn down very low and gently simmer for 30 minutes.

A couple of minutes before it’s cooked, throw in your Asian veggies and gently cook until they are wilted but still crunchy.

Serve in deep bowls seasoned with fish sauce and soy sauce, sprinkle with herbs, cress, spring onion and chilli and then serve with a lime wedge
