Start by prepping the prawns - wash and pat dry. Season with salt and set aside for 10 minutes.
Heat the oil in a pan, add garlic and stir for 30 seconds. Add in the prawns and cook for approximately 1 minute on both sides, the prawns should curl up and be a beautiful pink. Prawns cook very, very quickly and you don't want to overcook them and make them rubbery. Cool them down for 5-10 minutes and slice each piece in half.
Take some lukewarm water in a shallow plate or bowl. Dip the rice paper sheet in for about 15 seconds.
Transfer to a wet chopping board, this would make it easier to work the rice paper without breaking it.
Place your 3-4 pieces of each of the sliced veggies, 3 pieces of the halved prawns, and roll it all up.
Repeat and enjoy with sweet chilli sauce!
