Marinate the chicken with curry powder and milk. Let it sit overnight.

Heat a pan over medium heat and add butter. Once the butter melts, add the marinated chicken and cook until done. Set aside.

In another pan, heat oil over medium heat. Add the onion and sauté, then add the bell pepper. Cook until soft, then mix with the cucumber. Dissolve the date powder in the broth, squeeze in the lemon juice, and mix everything together.
