We had this dish at a supper club in Wisconsin 10 or 15 years ago, and it took me months to come up with the recipe. Actually, it took about three bites - the months were the time I spent waiting for veal to be on sale. Fortunately, with the cheese on top, you can't eat too much of it, so it doesn't take a lot of the veal. Measurements are approximate. If you're cooking for one, you can cook enough spaghetti for one serving and refrigerate half the veal mixture for reheating the next day.
This is a variation on a recipe my mum used to make when I was growing up. It is so comforting and relatively easy to put together. I serve it with mashed potatoes and green peas and beans. She used to serve it with tinned mushrooms in a butter sauce heated up slowly. I however think it would be better with a creamy fresh mushroom sauce. I cannot post the recipe as yet, because it is still a work in progress. This recipe is quite forgiving, you could use chicken breasts or even pork steaks if you preferred, but you would have to change the cooking time appropriately.
