Cut the pointed cabbage into quarters lengthwise and slice it very finely.

Rinse the bell pepper and remove the seeds and pith. Cut it into very small cubes.

Wash the apple and cut it into quarters. Remove the core and cut it into very small cubes.

Mix the finely sliced pointed cabbage and the cubes of apple and bell pepper in a bowl. Add slices of pickled red onion to the salad.

Whisk lemon juice, sugar, and oil together in a bowl and season the dressing with salt and pepper to taste.

Serve the salad as a side dish to meat or stews that need a green accompaniment.
