Grease an ovenproof dish and place the uncooked gnocchi in it.
Combine pasta sauce, cream and spinach if using, in a pan heating a few minutes then pour over gnocchi.
Sprinkle with cheese and bake approximately 40 minutes or until golden.
Notes
Bacon, mushrooms, zucchini, capsicum, eggplant would all be good additions to this dish, if using just fry off for a couple of minutes in olive oil before adding sauce and cream.
