Season the chicken breasts with salt and pepper on both sides
Heat ½ tbsp olive oil in a large skillet over medium high heat and brown the chicken breasts for 3-4 minutes on each side or until fully cooked. Transfer to a plate and keep warm.
Add the remaining ½ tbsp of olive oil to the same skillet and saute the minced garlic for 30 seconds.
Pour in ¼ cup of white wine. Deglaze the skillet, scraping the bottom to release any bits and pieces of chicken stuck to the bottom, and simmer until reduced by half.
Mix in the chicken broth, heavy cream, Italian seasoning, cheese, baby spinach, and sun-dried tomatoes. Simmer (don’t boil) until slightly thick and the spinach has wilted.
Transfer the chicken breasts back to the skillet, and cook until heated through, about 2 minutes. Serve over freshly cooked spaghetti or white rice.
