To make the dressing stir the tamarind paste, fish sauce, juice 1/2 lime, sugar and sambal oelek in a small bowl. Set aside
Pour the juice of the 1 lime into a bowl. Cut the apple into matchsticks and toss straight into the lime juice to stop the apple from discolouring. Cut the ‘cheeks’ from the mango. Score the flesh into cubes and scoop out with a spoon. Chop the flesh remaining on the stone into cubes. Peel and core the pineapple and cut the flesh into chunks. Cut the cherry tomatoes into quarters and the cucumber into pieces. Add the fruit and the vegetables to the bowl.
Add the chopped and picked herbs to the fruit mixture and pour over the dressing. Toss gently to distribute the dressing. Put the salad into a serving bowl or plate and scatter the peanuts and sesame seeds over the top.
