Cook the sweet potatoes in a large pan of boiling water for 10 minutes until tender. Drain well.
Meanwhile, heat the oil in a large non-stick frying pan and cook the onion and courgettes for 5 minutes until softened. Add the spring greens, sweet potatoes and chick peas, and cook for 5 minutes more.
Roughly break up the mixture with a fork and spoon over the harissa paste. Flatten down lightly and cook for a further 8 minutes, without stirring, until cooked through, crispy and golden on the bottom. Divide between plates and scatter with fresh chilli.
