Ina large pot, heat up the oil and add the finely chopped onion. Saute for 3-5 minutes until translucent.
Add the diced carrots and 50 ml of water and saute for 5 minutes.
Then add the bacon, sliced in larger pieces, chopped up parsley stalks (save the leaves for later), grated garlic, bay leaves and 50 ml of water and saute for 5 min.
After that add the paprika and tomato pure and fry for a minute until just fragrant. At that point add the beans and saute for 2 more minutes.
Pour with 2,5 l of water, add salt and pepper and bring up to boil. Then reduce the heat to medium high and cook for 45 minutes, without a lid.
If you'd like to add the sausages, cook them separately until half way done and add to the beans for the last 15 minutes of cooking time.
When cooked, taste and adjust the seasoning. Turn off the heat and add the chopped parsley leaves and stir well.
