This recipe is wonderfully adaptable to different tastes and dietary needs. For a lighter version, you can use low-fat cheeses and increase the proportion of marinara sauce to create a saucier dish without added calories. For those who love a bit of heat, adding red pepper flakes or diced jalapeños to the sauce can provide a spicy kick. To make this dish gluten-free, ensure your marinara sauce and chicken broth are certified gluten-free. You can also vary the herbs, using a mix of parsley, oregano, or thyme for different flavor profiles.
