Prep the quinoa and veggies: Cook quinoa according to package directions and let it cool. Grate zucchini and carrots, then squeeze the zucchini in a clean towel or cheesecloth to remove extra water.
Mash the chickpeas: Drain the chickpeas and smash them lightly with a fork or potato masher.
Chop and mix: Finely chop the bell pepper and green onions. Add them to the mixing bowl with quinoa, grated carrot, and squeezed zucchini.
Add the dry and wet seasonings: Sprinkle in garlic powder, onion powder, cumin, smoked paprika, salt and pepper. Pour in soy sauce and crack the egg into the bowl. Stir until combined.
Bind with breadcrumbs: Add breadcrumbs little by little until the mixture holds together.
Shape the patties: Form into patties about the size of your palm, pressing them firmly.
Heat the skillet: Add olive oil to a nonstick skillet over medium heat.
Cook until golden: Fry the patties for about 4 minutes per side until golden and crisp.
Rest and serve: Let the patties rest for a minute before serving.
Notes
Ensure to squeeze out excess water from zucchini to avoid soggy patties. Scale the size of patties for even cooking.
