Using a mandolin with a "toothed" blade, slice zucchini into long noodle-like shapes.
If you don't have a mandolin to do this, use a vegetable peeler and create long papardelle-like ribbons. Place zucchini into a big bowl. Season with ¼ teaspoon of salt and fresh cracked pepper. Mix well and set aside.
In a food processor, add Italian parsley, basil, garlic cloves, and a pinch of salt. Pulse several times to combine. Turn the machine on and slowly drizzle in the olive oil. Add ½ cup of pesto to the zucchini pasta. Mix to combine. Add more sauce if so desired. Serve right away or cover tightly and let it marinate for a few hours.
Garnish with Parmesan cheese, red pepper and a squeeze of fresh lemon juice.
