Spiralize zucchini, put in a colander and sprinkle with the salt. Let sit for 15-20 minutes. This pulls water out of the zucchini so that it doesn't get soggy. RINSE WELL and pat dry.
Saute minced garlic and olive oil for 30 seconds.
Add zucchini noodles. Saute for 4-5 minutes on a medium heat.
Remove from heat and add grated cheese.
Use firm, unpeeled zucchini for best results.
