- Cook the pasta in a large saucepan of boiling water according to the packet instructions. Meanwhile, mix together the parsley, mint, chives and tarragon with the tomatoes in a large bowl (the bowl should be large enough to take the cooked pasta too). Add pepper, then stir in the yoghurt.
- Drain the cooked pasta thoroughly, shaking the shapes in a colander to make sure that there is no cooking water trapped in them. Add the hot pasta to the herby yoghurt dressing and use a large spoon to stir them until they are thoroughly coated. Cover and set aside to cool until it reaches room temperature.
- Meanwhile, to make the salsa, mix together the celery, green capsicum, cucumber and spring onions. Stir in the lime zest, if using, and the watercress. Cover and set aside.
- Shortly before serving, stir the oil into the salsa with pepper to taste. Quarter, core and finely dice the apple, leaving its peel on. Add to the salsa and stir well.
- Halve the avocado and remove the stone, then cut it lengthways into quarters and peel off the skin. Dice the flesh and fold it into the pasta salad.
- Serve the cucumber salsa as an accompaniment to the pasta so that it can be added to taste. (The hot pasta absorbs its yoghurt dressing, becoming quite dry as it cools, so the cucumber salsa acts as a second dressing.) Garnish the pasta with sprigs of mint before serving.
