Ingredients

1 pound dried whole-wheat fusilli pasta

1 cup hulled pumpkin seeds, toasted

1/2 cup fresh flat-leaf parsley

1/4 cup coarsely chopped fresh chives

1/4 cup extra-virgin olive oil

1 garlic clove

1 3/4 teaspoon coarse salt

1 teaspoon finely grated lemon zest

2 1/2 ounces baby spinach, packed (2 1/2 cups)

Freshly ground pepper

3/4 cup part-skim ricotta cheese, for serving

Tomatoes, cut into wedges, for serving (optional)

Preparation

Bring a large pot of water to a boil. Add pasta, and cook until al dente. Drain, reserving 1/2 cup cooking liquid.

Meanwhile, combine toasted pumpkin seeds, parsley, chives, oil, garlic, 1 1/4 teaspoon salt, the lemon zest, and 1 cup baby spinach in a food processor. Season with pepper, and pulse until well combined.

Toss pasta with pesto mixture. Add reserved cooking liquid, and mix until pasta is well coated. Fold in remaining 1 1/2 cups baby spinach. Sprinkle with remaining 1/2 teaspoon salt. Divide among 6 bowls. Top each with a dollop of ricotta, and season with pepper. Serve with tomato wedges if desired.
