Bring out and measure all of your ingredients.
Grate zucchini, place into a strainer and sprinkle with salt.
Let sit for at least 15 minutes, (30 minutes is ideal, to get the moisture out) and toss your zucchini a couple of times.
Knead or press zucchini against the bottom and sides of the strainer pushing the water through.
Use paper towel to squeeze the zucchini. Do this until there is almost no more water coming out.
In a large bowl, combine the zucchini, feta or Parmesan, garlic, onion (or green onion), parsley, bread crumbs and egg.
Season with salt and pepper.
Depending on the amount of water left in your zucchini, you may need to add more bread crumbs so that you can form the mixture into "cakes" or "burgers".
