Dice the onion, press the garlic and cut the chilli pepper into rings. Fry in a pan with 1 tablespoon olive oil until translucent.
Then add the diced sweet potatoes. After a short time add the aubergine and zucchini cut into cubes as well as the drained beans and tomatoes from the can. Season the whole thing with the spices and after 5 minutes add the vegetable stock. Cook until the potatoes are tender.
Fresh flatbread or wholemeal bread goes well with it.
