In a large mixing bowl, combine the thinly sliced cabbage, grated carrot, and thinly sliced green apple.

Add the finely chopped spring onion and, if using, the chopped dill or parsley.

Drizzle the salad with the juice of 1 lemon and a generous splash of olive oil.

Season with salt to taste and toss everything together until well combined.

Let the salad sit for a few minutes to allow the flavors to meld together.

Serve immediately, or chill in the refrigerator until ready to serve.
