Heat a dry frying pan, add the walnuts and toast for a few minutes until fragrant and golden.
Place half of the toasted walnuts into a mini food processor along with the oil, vinegar, pomegranate molasses and syrup. Whiz until combined. It will be slightly chunky.
For the salad
Gently toss the rest of the salad ingredients together in a large bowl.
To serve
Divide the salad onto plates and serve drizzled with the dressing and sprinkled with the remaining walnuts, plus parsley and pomegranate seeds.
Notes
If you can't find pomegranate molasses (it's in many major grocery stores), then just leave it out. You can't substitute regular molasses or drinking pomegranate juice.
