Restované zelí

Quarter the head of cabbage and cut it into strips 0.5-1 cm wide, from the tip to the base. Throw away the broom.

In a large, heavy-bottomed pan, heat the oil over high heat and fry the chopped onion and cabbage for 5-6 minutes, stirring, until the cabbage starts to stick in places. Reduce the heat, add the butter, a little salt and pepper and simmer for another 4-5 minutes until the cabbage is soft. Season with vinegar or lemon juice as needed and serve immediately.
