Yellow zucchini was used in the pictures to make it look more like pasta, but you can just use a regular green zucchini.
Once you mix the zughetti with the sauce, serve immediately. As the zughetti sits, the salt from the sauce will draw water from the noodles, so it's best to eat it right away.
Keeps for 2 days in the refrigerator, but the longer it sits, the more watery it becomes.
