Combine all ingredients, aside from the olive oil, in a large bowl.
Pour a tablespoon in a large skillet or griddle over medium heat. Using your hands, form 12 patties with the quinoa mixture. Place patties on the skillet, working in batches if necessary.
Let quinoa patties cook for about 5 minutes before flipping and cooking another 5 minutes on the other side. Cakes should be lightly browned. Remove to a plate and continue cooking remaining patties. You might need to add another Tbsp olive oil to the skillet in between batches.
Serve with Greek yogurt mixed with sriracha and lime juice.
