3 tablespoons freshly grated Parmesan cheese; for garnish
DIRECTIONS:
For dressing, combine all ingredients in food processor and blend well. Set aside.
Cook pasta as directed on package; adding beans 7 to 5 minutes before end of cook time. Continue to cook until pasta is al dente and beans are just crisp-tender. Drain thoroughly. Stir in enough pesto to coat well. Set aside to cool. Finally, add drained artichoke hearts and one-half sliced onions; toss with remaining dressing. Store in refrigerator; warm to room temperature to serve.
To serve, turn into large lettuce-lined salad bowl or divide among lettuce-lined individual salad plates. Sprinkle with Parmesan and remaining green onions.
NOTE:
For plain pesto dressing, substitute 2 tablespoons pine nuts for tomatoes.
