5 Stars, the prosciutto (subbed for the pancetta) and the finely grated grana padano really set this apart. This makes a large casserole; I used a lasagna pan to make sure I had room. I think one very large onion would be enough, and then it would have fit in a 2 1/2-quart casserole dish. Served with Chinese Drunken Prawns #286999, so the chopped onion blended in with the rice and the shrimp. DH is lukewarm on zucchini/courgettes in general, but when zucchini is dressed up like this, he loves it. I think there is enough to easily serve 6 people as a side dish. Thanks for posting.
