In a large skillet add olive oil and cook the chicken on medium high heat for 3-5 minutes on each side or until brown on each side and cooked until no longer pink in center. Remove chicken and set aside on a plate. Drain oil and wipe out pan with a paper towel.

Add the heavy cream, chicken broth, garlic powder, Italian seasoning, and Parmesan cheese. Whisk over medium high heat until it starts to thicken. Then add the spinach and tomatoes and let it simmer until the spinach just starts to wilt then add the chicken back to the pan, turning each one after adding to coat the chicken in the sauce.

Heat for a few minutes on a low simmer to heat the chicken through. Serve over pasta.
