Cut the sausages into slices, chop the peeled onion and fry both in a pan with a little oil. Meanwhile, peel and dice the potatoes. Add the chopped tomatoes, corn, beans, potatoes and the chilli pepper and fill up with the broth. Let simmer for about 15 minutes. If you want, you can also dice a bell pepper and add it to the pan.
When the potatoes are almost done, add the curry ketchup and spices and simmer for another 5 minutes.
Serve hot. A fresh baguette or a green salad tastes great with it.
