In a small bowl, mix together 1/3 tsp salt, 1/3 tsp pepper and 1/2 tsp granulated garlic. Add the prawns and toss to coat.
Heat 2 tbsp of cooking oil to medium-high.
Fry the prawns for 4-6 minutes, turning occasionally, until they turn opaque and are cooked inside.
Transfer to a plate to cool down.
In another bowl, whisk together 1 tbsp fish sauce, 1 tbsp lime juice and 1 tsp brown sugar until the sugar dissolves.
Add 1/2 tsp minced garlic, 1 tsp dried shrimp or 1/2 tsp shrimp paste, if using. Whisk to combine.
If you are skipping fresh chilies, add 1/3 tsp dried chili flakes to the dressing.
Place shredded papaya, tomato halves, sliced snow peas, sliced chilies, the prawns and most of the peanuts into a large bowl.
Pour in the dressing and gently stir to combine.
Garnish with Thai leaves and the remaining peanuts and serve immediately.
