Heat 1 tbsp vegetable oil in a frying pan over medium heat and cook 12 large green (raw) king prawns (shelled and deveined) for about 2 minutes each side or until they just change colour. Remove from heat and cool.

Quickly dip a round rice-paper sheet into a bowl of warm water, then drain. Place on a clean tea towel and top with 1 prawn, 1 small butter-lettuce leaf, 1 strip red capsicum, 2 carrot sticks, a few bean sprouts and a sprig of coriander.

Fold in the sides of the rice paper and roll up firmly. Repeat with 11 remaining rice-paper sheets, prawns, vegetables and coriander.

Serve with 1 cup hoisin sauce for dipping.
