For the zucchini I used a mandolin with the julienne accessory. To use the mandolin I removed the tips from the zucchini and then just run it through the mandolin. Stop when you get to the seeds and rotate to continue on the other side. This is because that section is more spongy and tends to turn to mush when cooked. You can use that part for stocks and soups.
Another thing that you can use is a potato peeler. You run it down the zucchini to get thick strips and then you cut those lengthwise to get the noodle shape. Also remember to not use the center of the zucchini.If you use a spiralizer or the spiralizer Kitchen Aid accesorry then just put the zucchini in place and follow the instructions to make the pasta.
