Why use penne rigate? The ridges (and the hollow center) help capture more pesto. Peppery arugula does double duty: First it's blended with garlic, Parmesan, lemon juice, and toasted almonds for sauce. Then whole leaves are scattered over the dish.
Add the asparagus to the pot of boiling water with the fettuccine during the last five minutes to cook both vegetable and pasta at once. Goat cheese melts into the hot pasta with grainy mustard and dill to create a creamy, tangy sauce.
