Once cooked, drain the beans well and place them in a food processor. Chop the previously cooked beets and add them to the beans, as well as the grated carrot, the onion, and the chopped garlic cloves. Add the olive oil and seasonings and blend until smooth. Bring the mixture to a simmer and gradually mix in the ground flaxseed and the oat flour, stirring well to form a paste. Pour the mixture onto a clean surface and, with your hands, make small balls and spread them out to form the hamburgers. Cook the hamburgers in the oven or in the frying pan until golden brown.
