Cook quinoa with water in a saucepan until done. Drain excess water and set aside to cool.

Heat oil in a pan. Add chopped onion and sauté until soft.

Add grated carrot, boiled sweet corn, and chopped spinach to the pan.

Cook until all vegetables are soft. Remove from heat and let it cool.

In a mixing bowl, combine cooked quinoa, sautéed vegetables, corn flour, black pepper powder, red chili flakes, salt, and a teaspoon of cooking oil.

Mix all ingredients thoroughly.

Shape the mixture into patties using your palms.

Heat a skillet with some oil.

Place the vegetable quinoa patties on the hot skillet and cook on both sides until golden brown and evenly cooked.

Transfer the patties to a serving platter and serve hot.
