In the same skillet, melt the butter and add minced garlic. Sauté for about a minute until it’s fragrant (seriously, is there anything better than the smell of garlic cooking?). Stir in the chicken broth, heavy cream, and Parmesan cheese, whisking until the sauce is smooth. Add the sun-dried tomatoes, spinach, and Italian seasoning, and let everything simmer for a few minutes until the spinach wilts and the sauce thickens slightly.
