In a large bowl, combine quinoa, eggs, salt, and lemon pepper.
Stir in parsley, onion, parmesan cheese, and garlic.
Add breadcrumbs, chopped carrot, and zucchini. Mix well and let sit for a few minutes so the breadcrumbs absorb moisture.
Shape the mixture into about 20 thick patties. Adjust texture with more breadcrumbs if too wet, or a few drops of water if too dry.
Heat oil in a large skillet over medium-low heat.
Cook 5–6 patties at a time, cover, and cook for 7–10 minutes until deeply golden on the bottom.
Carefully flip and cook the other side for about 5 minutes until golden.
Remove and repeat with remaining patties, adding oil as needed. Serve warm.
