Step 1

Heat the oven to 200C/180C fan/gas To make the sauce, chop 2 green chillies (deseeded, if you prefer) and tip into a food processor with a bunch of coriander, the spring onions, lime juice, caster sugar and fish sauce (leave this out of a portion of the sauce if you’re making the vegetarian bao). Blend, then tip the mixture into the rapeseed or sunflower oil and set aside.

Step 2

Cut the sweet potato into large wedges, toss in oil and some seasoning, tip onto a baking tray and bake for 40 mins until brown at the edges and tender.

Step 3

Cook the breaded prawns or fish goujons and karaage or breaded chicken following pack instructions.

Step 4

Microwave or steam 18 bao buns following pack instructions until hot.

Step 5

Fill the warm bao with either the chicken, prawns or fish, or sweet potato, some slaw (see recipe below) and green sauce.
