Heat 1 tablespoon of olive oil in a non-stick skillet over medium heat. Cook thin sliced chicken for about 3 or 4 minutes per side, seasoning with garlic pepper as it cooks. When chicken is cooked through and no longer pink in center, remove from heat and transfer to a cutting board. Chop chicken into small bite-size pieces, squeeze the juice from half a lemon over the top and toss to combine. Allow to cool while assembling the salad.

In a large mixing bowl combine cooked and cooled pasta, romaine, tomatoes, green onion, and basil. Add Caesar salad dressing and toss to combine. Add cooked, chopped chicken (which should be slightly cool by now), plenty of fresh ground black pepper, and the croutons. Toss again, sprinkle with shaved Parmesan and serve.
