Slice the chicken breasts into thin strips. Add the spices, yogurt, vinegar, and lemon juice, and mix well. Let the chicken marinate for at least 2 hours.

Slice the onion, bell peppers, and tomato.

Heat a skillet with some oil over medium heat. Add the chicken and cook, stirring, until it releases its juices and the liquid evaporates.

Add the onion to the chicken and stir together. Then add the bell peppers and tomato, continuing to stir until the chicken is fully cooked.
