Heat olive oil in a large frying pan on medium-high heat. Pound out chicken using a meat mallet so that it is ½ inch thick.** Lightly season each side of the chicken with salt, pepper, garlic powder, and onion powder. Then generously season each side with Italian seasoning.
Add the chicken to the frying pan and cover. Cook for 4-5 minutes, or until golden brown. Flip the chicken over and cook for 3-4 minutes, or until golden brown. Move the chicken to a plate and cover. Allow to sit for about 10 minutes before slicing the chicken. Slice the chicken into strips, going against the grain.
Add the cooked pasta, cherry tomatoes, cucumber, olives, red onion, mozzarella pearls, and sliced chicken to a large bowl, and mix.
Add Italian dressing to the salad, starting with 1 cup and adding more according to your taste preference. Eat immediately, or store in the fridge and eat cold. Enjoy!
