This dish derives its name from the color contrast of the two types of pasta. Because it mixes the earthiness of whole wheat with the familiarity of regular pasta, it's a delicious introduction to whole-grain pastas. Truffle oil adds a pleasant, earthy undertone; you can substitute extravirgin olive oil. As with all alfredo dishes, serve immediately.
Forget everything you know about tuna cakes. Simple, cheesy and held together with hearty stuffing, these'll win over even those determined not to like seafood.
