Wash the cabbage leaves and cut the thick panicles flat. Blanch the cabbage leaves in salt water for about 5 minutes. Take them out, rinse them under cold water and let them drain on a tea towel.
Peel and slice the carrots. Peel onions. Chop 1 onion finely. Halve 1 onion and cut into thin strips. Soak toast in cold water. Cut the 2 smallest leaves of cabbage into thin strips.
Cut the bacon into strips. Wash parsley, shake dry and chop the leaves finely.
Heat the oil in a pan. Fry the onion cubes, bacon and cabbage strips for 5-7 minutes, then place in a bowl. Press the sausage meat into the bowl. Add minced meat, squeezed bread, parsley and egg and knead into a mass with the dough hooks of the hand mixer.
Add cabbage-bacon mix, season with salt and pepper.
Melt butter in a casserole. Fry the carrots and onion strips for 3-4 minutes, season with salt and pepper.
Place two cabbage leaves staggered on top of each other and place in a medium sized soup ladle. Pour in 1/8 of the meat mixture and close to a packet. Take the packet out of the ladle and tie up with kitchen string.
Place the parcel on top of the carrots in the casserole dish. Pour in white wine and stock and cover and braise in the preheated oven (electric cooker: 175 °C/ circulating air: 150 °C/ gas: see manufacturer) for 35-45 minutes.
