Prepare the Marinade: In a bowl, mix the onion powder, paprika, cumin, salt, and black pepper.

Add the olive oil and lemon juice to form a marinade.

Marinate the Chicken: Add the chicken pieces to the marinade and mix well to coat. Let it marinate in the refrigerator for at least 30 minutes (ideally 1 to 2 hours).

Cook: Heat a skillet over medium heat. Add the marinated chicken and cook for about 6 to 8 minutes on each side, or until the chicken is cooked through and golden.

Serve: Serve hot, garnished with chopped fresh parsley, with rice, grilled vegetables, or in a wrap.
