Making the Dish
Grind the walnuts in a food processor until chopped but not overprocessed (avoid mincing or forming a paste).
Cook pasta in a large pot until almost al dente; drain and reserve one cup of cooking water.
In a very large sauté pan, cook the nuts, garlic, and parsley in the olive oil over low heat until the garlic is soft, about 8-9 minutes.
Add pasta and gently mix to combine with sauce.
Add as much of the reserved cooking water as you need to get the sauce consistency you like—probably 1⁄4 to 1⁄2 cup.
If using cheese, add pecorino to pasta and serve immediately.
