Here is a lovely twist on beloved pesto for spring. Baby spinach takes the place of most of the basil to give the sauce an earthy flavor. The thick, emerald sauce beautifully coats the flat noodles and serves up big flavor in every forkful.
1. Place spinach in a microwave-safe bowl; cover bowl with plastic wrap. Microwave at HIGH 2 minutes or until spinach wilts. Remove plastic wrap; cool slightly.
2. Place spinach, almonds, and next 5 ingredients (through garlic) in a food processor. Process until chopped. Add broth, juice, and salt; pulse 5 times. With processor on, slowly pour oil through food chute; process until well blended. Scrape into a bowl; stir in half of cheese. Cover with plastic wrap.
3. Cook pasta according to package directions, omitting salt and fat. Drain. Toss pasta with 1/2 cup pesto. Arrange about 1 1/2 cups pasta mixture in each of 4 bowls; top each serving with 2 tablespoons remaining pesto and 1 1/2 teaspoons remaining cheese.
