small handful crispy onions or fried garlic chips (optional)
1 red chilli (optional)
1 tbsp brown sugar
juice 2 limes
2 tsp fish sauce
To make the dressing, bash the chilli (if using) using a pestle and mortar. Add the remaining ingredients, mix together and taste for a good combination of sweet, sour, salty and hot, then set aside.
Combine the prawns, mint, coriander, lychees, beansprouts and half the peanuts with the dressing, and toss well. Pile onto a serving platter and scatter with the remaining peanuts and the garlic chips or crispy onions (if using). Put in the middle of the table and let everyone help themselves.
