Bring the water with the granulated broth to the boil. Stir in the oatmeal and remove from the heat. Put on the lid and let the mass swell.
In the meantime, peel the onions and cut them into cubes. Sweat the onion cubes in a pan with the sunflower margarine until light brown.
Beat the eggs in a bowl until frothy. Stir in the breadcrumbs, the salt and the remaining spices as well as the parsley and mustard. Add the swollen oatmeal and the browned onions. Mix everything together well (preferably with a fork). Moisten your hands, form patties from the mixture and fry them in olive oil until light brown.
Put the apple red cabbage in a saucepan. Add the water, oil and granulated broth and simmer for 15 minutes with the lid closed.
Peel the potatoes, wash eighths and cook in salted water for about 15 minutes. Drain the potatoes and pound them finely with a potato masher. Pour in the previously heated hot milk with nutmeg and salt and stir everything until frothy.
Arrange the patties with the mashed potatoes and red cabbage on plates and serve.
The Boss Kitchen editorial staff oversees content review, fact-checking, and recipe verification across the site. Published articles pass through the editorial team before going live, ensuring ingredient lists, techniques, cooking times, and nutritional claims hold up in a home kitchen. The team coordinates contributions across the site writers, handles reader corrections, and maintains consistency in measurement conventions, safety guidance, and dietary labeling. Posts under this byline typically represent team-reviewed reference material, site announcements, or editorial roundups rather than individual-author features, and they are held to the same sourcing standards as bylined recipe and product coverage.
