Wash and peel the kohlrabi, then cut into thin slices. Peel the onion and chop finely.
Heat the olive oil in a non-stick pan over medium-high heat. Add the chopped onion and minced meat. Fry for 4 minutes, stirring occasionally, until the meat is browned.
Add the kohlrabi slices and sauté for 2 minutes.
Deglaze the pan with vegetable stock and reduce heat to medium. Simmer for 15 minutes until the kohlrabi is tender.
Stir in the cream and season with sea salt and freshly ground pepper to taste.
