12 ounces baby arugula washed and spun dry
4 medium garlic cloves, peeled
1 teaspoon freshly squeezed lemon juice
1/2 cup hulled, toasted pumpkin seeds
1/2 cup finely grated Pecorino Romano
1 teaspoon fresh ground pepper and salt if used (depending on how salted your pasta water is)
2/3 cup of Picual, or Hojiblanca Extra Virgin Olive Oil
Cook your pasta based on the instructions.
Meanwhile, combine arugula, garlic, lemon juice, half of the cheese, pumpkin seeds, in a food processor. With the motor running, slowly drizzle in olive oil and process until evenly blended until finely processed. No more than a minute tops. Season well with salt (if using) and freshly ground black pepper.
Drain pasta and toss with the arugula pesto and mix until evenly combined. Serve immediately using reserved cheese sprinkled on top.
