To begin making the Vegetable Quinoa Patty, cook quinoa and let it cool.
Cook 1 cup of quinoa with 2 cups of water on low flame with the lid on in a saucepan or any regular pan. Drain the excess water and keep the quinoa aside.
In the meantime, heat some oil in a heavy-bottomed pan. Add onion and cook until it becomes soft.
Once the onions become soft, add carrot, corn kernels, and spinach. Cook until all the vegetables become soft. Once done, turn off the heat and let it cool down.
In a mixing bowl, add the cooked quinoa, sautéed veggies, corn flour, pepper powder, red chili flakes, salt, and teaspoon of cooking oil. Do not add any water. Check the salt and spices and adjust according to taste.
Mix everything properly and make Vegetable Quinoa Patty with the help of your palms.
Heat a skillet with some oil. Once it is hot, add the Vegetable Quinoa Patty and cook it on both sides until it becomes evenly brown.
Transfer the Vegetable Quinoa Patty onto a serving platter and serve hot.
