In a small mixing bowl, combine red chili sauce, minced garlic cloves, finely chopped long red chili, red chili powder, and a pinch of black pepper and salt. Mix well to create a smooth dressing.

Peel and dice the ripe mango into small cubes, thinly slice half a red onion, and chop a handful of fresh mint and coriander leaves.

On a large serving platter, layer the mango cubes, medium-sized cooked prawns, and sliced red onion.

Drizzle the homemade dressing generously over the salad components. Gently toss all the ingredients together.

Serve immediately for the freshest flavor, or keep components separate if prepping in advance.
