If you do not already have cooked quinoa, prepare it at this time. 2/3 cup uncooked quinoa will yield ~2 cups cooked.
Shred sweet potato using either the coarse side of a box grater or the grater attachment of a food processor.
Heat a large pot or rimmed skillet over medium heat. Once hot, add oil, onion, sweet potato, garlic, salt, and pepper. Sauté for 4-5 minutes, stirring frequently, or until the onion and sweet potato are tender and fragrant. Add chopped greens and stir to slightly wilt. Set aside.
Add eggs to a medium mixing bowl and whisk until well combined. Set aside.
To a large mixing bowl add sautéed vegetables, cooked and cooled quinoa, salt, and curry powder (optional) and stir. Then add eggs and stir. Lastly, add gluten-free flour and stir until combined. You should have a slightly tacky but moldable mixture. Add more gluten-free flour as needed if too wet to handle.
Form into thin (roughly 1/4-inch-thick) patties the size of the palm of your hand. In the meantime, heat a large rimmed skillet (we prefer cast iron).
Once hot, add a little oil to coat the pan and enough fritters to comfortably fit without crowding. Pan fry until golden brown — ~ 4 minutes on each side.
Optional: For even crispier fritters, continue baking in a 400 degree F (204 C) oven for 10-15 minutes.
Serve hot with garnishes of choice, such as lemon juice, dairy-free yogurt, hummus, garlic dill sauce, or fresh herbs (all optional). Store leftovers covered in the refrigerator up to 3-4 days, or in the freezer up to 1 month. Reheat on the stovetop over medium heat, in a 350 degree F (176 C) oven, or in the microwave until hot. If frozen, thaw before reheating.
