Season the chicken breasts with salt and pepper and brown them in a large skillet with ½ tbsp olive oil, over medium high heat for 3-4 minutes on each side or until fully cooked.
After browning the seasoned chicken breasts and transferring them to a plate, add ½ tbsp of olive oil to the same skillet and saute the minced garlic for 30 seconds.
Pour in the white wine to deglaze the skillet, scraping the bottom to release anything stuck to it, and simmer until reduced by half.
Add the chicken broth, heavy cream, Italian seasoning, parmesan cheese, spinach, and sun-dried tomatoes. Simmer until slightly thick and the spinach has wilted.
Return the chicken breasts to the skillet and cook until heated through. Serve over freshly cooked spaghetti or white rice.
