1. Wash the zucchini.
2. Peel them, leaving a strip of skin on two sides.
3. Cut them into very thin slices.
4. Slice the onion.
5. Heat the olive oil in a pan (2 to 3 tablespoons, depending on how greasy you like to cook!).
6. Sauté the onion over low heat for about 5 minutes, then add the zucchini and cook for about 30 to 40 minutes. The zucchini should release their water and be well cooked, almost falling apart.
7. Meanwhile, cut the chicken into thin slices, heat the oil in a pan, add the chicken and cook it. Then add the sour cream, curry powder (to your taste, I use a lot, I recommend tasting and adding until it suits you).
8. Pour the chicken with the cream over the zucchini.
9. Stir everything together, season with salt and pepper.
