One of the great things about casseroles is that they can be anything you want them to be. A recipe isn't really needed, just an idea of what you want for dinner and a few things that will help bring it all together. For those that do need a little guidance though, the recipe that follows is a great place to start.
In this dish, rounds of zucchini come together with ground beef for a delicious low-carb dinner. All that's needed to bring them together is a cheese sauce for it to all bake up in. Of course, that cheese can be whatever kind you fancy most, but here melty mozzarella is used. While this recipe is kept pretty simple, feel free to add anything else that you love to it such as peppers, mushrooms, or more. This is after all, your casserole!
