Wash lentils and bring to a boil with 2 times the amount of water. Then simmer gently for about 12 - 15 minutes.
When the lentils are soft, stir in the rolled oats and the red lentil flour or chickpea flour, alternatively potato flour. Add a little more water if necessary.

Preheat oven to 180 degrees Celsius top/bottom heat.
Form burgers from the mixture.

Bake the burgers in the oven for 20 minutes.
