2. A Creamy or Savory Binder: Cream sauces, broth, or a light cheese mix hold everything together.

3. A Flavor Boost: Garlic, onions, herbs, or festive spices.

4. A Crispy or Cheesy Topping: Breadcrumbs, mashed potatoes, or melted cheese.

Once you have the basics down, the possibilities are endless.
