Pound the chicken breasts to an even thickness if needed. This helps in cooking them uniformly.
In a small bowl, mix together the salt, black pepper, paprika, garlic powder, and onion powder.
Rub the chicken breasts with the seasoning mixture on all sides.
Heat the olive oil or coconut oil in a large skillet over medium heat.
Add the chicken breasts and cook for 6-8 minutes on each side, or until the internal temperature reaches 165°F (74°C) and the chicken is no longer pink in the center.
If using, drizzle the soy sauce and lemon or lime juice over the chicken during the last few minutes of cooking.
Transfer the cooked chicken to a cutting board and let it rest for a few minutes before slicing.
Enjoy your meal!
