1. Heat olive oil in a large skillet over medium heat. Season chicken breasts with salt, pepper, and Italian seasoning. Cook the chicken for 6-7 minutes on each side, or until golden and cooked through. Remove and set aside.
2. In the same skillet, sauté garlic and sun-dried tomatoes for 1-2 minutes. Add spinach and cook until wilted.
3. Stir in heavy cream, chicken broth, and Parmesan cheese. Bring to a simmer and cook for 3-4 minutes until the sauce thickens.
4. Return the chicken to the skillet, spooning the sauce over the chicken. Simmer for another 3-4 minutes to combine the flavors.
5. Garnish with fresh basil and serve hot, perfect over pasta or with crusty bread.
