This is a great from scratch Tuna Casserole. No canned soup here, an easy Parmesan cream sauce with just a touch of cayenne to give it a nice kick. Red bell peppers, green onions and mushrooms give it the right flavor and colors to pull an ordinary tuna casserole to over the top. This recipe comes from Art Smith's cookbook "Kitchen Life" which I am enjoying very much! When I make this again, I will probably substitute Ritz cracker crumbs for the dried bread crumbs to add a little more pizzaz to the top.
