Here's a nice twist on the old tuna casserole dish. Not real fond of the name, though. I guess if you add oregano & tomato to anything you can call it "Italiano". I usually double this recipe (teenage son).
1/2 cup chopped onion
1/4 Tsp oregano
2 Tbs butter
1 can Campbell's Cream of Mushroom Soup
2 cups cooked elbow macaroni
1/2 cup chopped canned tomatoes
1 can "decent" tuna
Cook the onion with oregano in butter until tender. Blend in the soup and then add the rest of the ingredients. You can either transfer to a baking dish or serve as is. Grated Parmesan cheese is great on top!
