One word... "gravy".
Combine the giblets, some garlic cloves, and some chicken stock. This is the time to add aromatics like celery and onions if that is what you like. Cover and bring to a boil. Uncover and reduce heat to a simmer. Skim off any gunk that has collected on the surface.
Cook the giblets uncovered for about one hour until the point of a knife or fork slides in easily. Add a cup of water each time the liquid reduces by half. Remove the giblets, allowing them to cool.
Meahwhile, continue to cook stock for an hour or so until the neck bones fall apart. Add water as needed. During the last half-hour don't add any more water. While that's going on, cut the heart and gizzards into thin slices or small cubes and set it aside. Strain the stock. Skim off any remaining fat. Just before serving, add your sliced/diced giblets and add herbs and such that suits you. Pick out the meat from neck and add. Heat until warm throughout. Add deglazing liquid from the roasted bird if you have any. Season to taste with salt and pepper.
If you are short of what you need, make up a reaux. This is what _my_ grandma called "brown gravy" (we weren't so fancy and didn't use french words). It's just butter and flour browned to just short of the color of creamy peanut butter. Mix this in with your giblet gravy and you're ready to go.
