Directions

1. To make pesto: attach multipurpose blade to KitchenAid® 7 Cup Food Processor. Place walnuts and garlic in work bowl and pulse 3-4 times until finely chopped. Remove walnuts into separate bowl. Add parsley and pulse until finely minced.
2. Return chopped walnuts and garlic to work bowl and pulse 2 to 3 times to combine. With Food Processor running on low speed, pour olive oil into narrow feed tube so oil slowly drizzles into pesto. Transfer pesto to medium bowl and stir in Parmesan cheese and black pepper to taste. Set aside until ready to use. Can be made 2 days ahead and stored in refrigerator.
3. Clean work bowl of Food Processor and attach multipurpose blade. One at a time, process carrots, celery, onion, potatoes and garlic pulsing 3 to 4 times to coarsely chop.
