1.Combine ingredients for palm sugar dressing in small saucepan, bring to a boil. Remove from heat, strain. Cool to room temperature.
2.Sprinkle salt evenly over fish. Cook fish on heated oiled grill plate (or grill or barbecue) until browned and cooked as desired.
3.Combine apple, onions, mint, coriander and juice in large bowl, pour over half of the palm sugar dressing, toss to combine.
4.Divide fish among serving plates; top with salad then cashews. Drizzle with remaining dressing.
You can also use ocean trout fillets in this recipe. Cooking times will change slightly for each different kind and thickness of fish you select. Salmon and ocean trout are at their best if slightly underdone. Don’t slice the apples until you are ready to toss the salad with the dressing because the flesh will brown when exposed to air.
