Trenette, so-called because they're thought to resemble train tracks, are a Ligurian version of linguine. (NOTE: Don't substitute pecorino romano for pecorino sardo.)
VARIATION: To use a food processor, place pine nuts, garlic, and salt in the processor bowl and blend to a paste. Add basil, drizzle in oil, and process until smooth. Transfer to a bowl and stir in grated cheese by hand.
