Salad
Place salad ingredients in a bowl. Whisk the dressing ingredients together until the sugar is dissolved, then pour over salad. Toss to combine.
Omelette
Place prawns and rice flour in a plastic zip-lock bag. Season. Shake to coat the prawns.
Combine the eggs, spring onion, sugar and fish sauce by whisking the ingredients.
Heat oil on a medium-high heat. Add prawns and fry until almost cooked. Reduce heat slightly and add egg mixture. Cook for a few minutes until the edges are firm and the center is almost set, then fold the omelette over. Cook for another minute or so. Cut into slices.
To serve
Place salad on plates. Top with warm omelette slices.
Drizzle with a little Lee Kum Kee Chiu Chow Chilli Oil. Sprinkle with fried shallots, fresh chilli and herbs.
