Wash and dice the cured pork. Clean, wash and chop the peppers. Peel and chop onion. Heat oil in a pot. Brown the smoked pork, paprika, onion and possibly 1 tbsp. caraway seeds briefly.
Add the sauerkraut. Season with salt, pepper and sugar. Cover and stew for about 15 minutes, then remove from heat.
Mix yeast and baking mix in a bowl. Add 350 ml lukewarm water and knead with the dough hooks of the mixer for about 3 minutes to a smooth dough. Cover and leave to rise in a warm place for about 30 minutes.
Preheat oven (electric cooker: 200 °C/circulating air: 175 °C/gas: see manufacturer). Grease a fat pan (deep baking tray; approx. 32 x 39 cm) and dust with flour. Whisk sour cream and eggs. Season with salt and pepper.
Roll out the dough on the fat pan, raising the rim a little. Spread the sauerkraut mixture over it. Pour over the mixture. Bake in the hot oven on the lowest rack for 35-40 minutes. Wash parsley, shake dry and chop finely.
Sprinkle over the finished quiche.
