Baked casserole, a perfect dinner dish Chicken, zucchini, mushrooms and tomatoes, what's not to like? Casseroles were a weekly thing when I was growing up. I was 1 of 3 kids in a family of 5, and casseroles were just an easy way to feed us all. I didn't always like the casseroles that were served, but I have come to appreciate their versatility, and have come to enjoy the variety of flavours and ingredients in them.
