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.
These skillet-grilled burritos come together in a flash thanks to store-bought rotisserie chicken. Keep this meal light by serving with a fresh green salad.
