Lettuce salad with feta cheese and walnuts

A variation of the classic Greek lettuce salad. Very tasty and easy to put together. It goes perfectly well with roast lamb or chicken

Ingredients (for 4-6 people):
1 small Roman lettuce
4 tender stalks of celery
2-3 leaves of Chinese cabbage (the bok choy)
300gr. feta cheese, cut in cubes
70-80gr. walnuts,  roughly chopped
salt
pepper
6 tbsp of olive oil
3 tbsp of white vinegar

Method:
Put the feta cubes in a bowl along with the olive oil, the vinegar and the pepper.
Leave the bowl out of the fridge for about half an hour to allow the feta to marinate.

In the meantime wash, dry and roughly chop the lettuce and the cabbage leaves. Put them in a salad bowl, add the celery finely chopped and toss with your hands.

Drain the feta off the marinade and leave aside on a plate. Season the marinade with salt and pepper and whisk until the ingredients blend well. Stir well so the dressing will coat the salad evenly.

Pour over the salad with the dressing and on top scatter the feta cubes and the walnuts.
Serve immediately
