Cook the penne pasta according to package instructions until al dente. Drain and set aside.
Season the chicken breasts with olive oil, garlic powder, Italian seasoning, salt, and pepper.
Heat a large skillet over medium heat and cook the chicken for about 6-7 minutes per side, or until cooked through. Remove from the skillet and let rest for 5 minutes before slicing.
In the same skillet, add the cherry tomatoes and cook for 2-3 minutes until they begin to soften.
Add the cooked pasta and sliced chicken to the skillet, tossing everything together.
Stir in the fresh basil and mozzarella cheese until well combined.
Drizzle with balsamic glaze before serving.
