Place the quinoa in a large bowl and set aside.
When chopping the vegetables, make sure they are uniform in size. Combine the chopped vegetables with the quinoa.
Add the onion, garlic, parsley, cheese and lemon juice to the mixture. Season to taste with salt and pepper, then mix well.
Add the beaten eggs to the mixture, then add the bread crumbs and combine. (If you aren’t on a gluten-free diet, I recommend using regular breadcrumbs.)
Let the mixture rest for 2 to 3 minutes, then form it into patties. (Add more bread crumbs if necessary; however, be sure to allow a few minutes for the moisture to absorb.)
Heat olive oil in a large skillet over medium heat.
Fry the patties to golden brown on both sides, flipping only once. Drain on paper towels.
