Make your flax egg: Add your ground flax seeds in a small bowl with water. Set aside.
Chop your onion and garlic. Heat 1 tablespoon of oil in a skillet over medium heat. Add the onions and garlic and sauté until translucent and fragrant, about 5 minutes. Remove from heat and set aside.
In a food processor, add your chickpeas, tahini and flax egg. Blend a few seconds until the chickpeas are almost smooth. Transfer to a medium mixing bowl.
Add the oats, carrots, sunflower seeds, cooked garlic and onions, oregano, cumin, coriander, salt, soy sauce and olive oil to the bowl. Mix it all together until combined.
With slightly wet hands, form 4 patties.
