Versatile Zucchini Patties

2 cups grated zucchini (or various vegetables; carrots, corn, etc)
salt
2 eggs, beaten
1/2 cup chopped onion
1/2 cup all-purpose flour
1/2 cup grated parmesan cheese
1/2 cup shredded mozzarella cheese
2 tablespoons vegetable oil

1. Spread zucchini. Lay out on paper towels or in a colander (with a bowl under it), sprinkle zucchini with salt and let rest for at least 30 minutes (I get best results when I let it sit for several hours). This step pulls out excess moisture from the zucchini/squash.

2. In a medium bowl, combine the zucchini, eggs, onion, flour, Parmesan cheese, mozzarella cheese (add seasoning at this time as well if you desire).

3. Heat a small amount of oil in a skillet over medium-high heat. Drop zucchini mixture by heaping tablespoonfuls, and cook for a few minutes on each side until golden.
