Using your mandolin or vegetable peeler — like the one seen on the show, thinly slice the zucchini into pasta lengthy strips. Stop peeling when you get to the seeded core of the zucchini.
Important step: Transfer the zucchini into a colander in a clean sink or over a towel, add 2 tsp of salt to the noodles and toss. This step allows the water in the noodles to drain, and the salt will help absorb some of the additional water. You will rinse the salt off in a later step. Let this set for about 30 mins. (This is a good time to make your pesto and other dishes.)
