Clean and wash the cabbage, cut into large pieces and cook in plenty of boiling salted water for about 3 minutes. In the meantime, toast the white bread slices until golden brown. Leave the bacon in a pan until crispy.
Bring the vegetable stock to the boil, season with cinnamon and pepper. Layer cabbage, white bread, bacon and 150 g cheese in a greased casserole dish. Pour the broth over the casserole. Cut remaining cheese into quarters and spread on the casserole.
Bake in the preheated oven (electric cooker: 175°C/ gas: level 2) for about 1 hour. 20 minutes before the end of the cooking time, spread fat in flakes on the casserole.
