Grind the oats: Use a food processor or blender to grind the oats until the flakes are broken up, but not as fine as flour.
To the mixing bowl, add your cooked quinoa, chickpeas, green onion, cilantro, parsley, garlic, olive oil, cumin, salt, cinnamon and red pepper flakes. Stir to combine. Use a potato masher or the paddle attachment of your mixer to mix really well. You need to mash up those chickpeas so the burgers hold together.
To prepare the cauliflower: Transfer the cauliflower florets to the bowl of your food processor. Pulse until they resemble a couscous-like texture, about 15 pulses. Pour the mixture into a large mixing bowl or the bowl of your stand mixer. Keep the food processor bowl handy because you’ll use it again soon.
To cook the quinoa: Rinse the quinoa in a fine mesh colander, then combine with ⅔ cup water in a small saucepan. Bring the mixture to boil, then cover and reduce heat to maintain a gentle simmer. Simmer for 15 minutes, then remove from heat and let the quinoa steam with the lid on for 5 minutes. Then drain off any excess water and set aside to cool.
