Cook the penne pasta according to package instructions until al dente. Drain and set aside.
While the pasta is cooking, heat olive oil in a large skillet over medium heat. Season the chicken breasts with garlic powder, Italian seasoning, salt, and pepper.
Add the seasoned chicken to the skillet and cook for about 6-7 minutes on each side, or until the chicken is cooked through and no longer pink in the center. Remove from the skillet and let it rest for a few minutes before slicing.
In the same skillet, add the cherry tomatoes and cook for 2-3 minutes until they start to soften.
Add the cooked pasta and sliced chicken to the skillet with the tomatoes. Toss everything together until well combined.
Stir in the chopped basil and half of the mozzarella cheese. Mix until the cheese is slightly melted.
Serve the pasta in bowls, drizzling each serving with balsamic glaze and topping with the remaining mozzarella cheese.
