Rinse the beans and add them to a mixing bowl. Mash, but leave half of the beans whole for a bit of texture.
Scoop the flesh out of the baked potato with a spoon and add to the bowl.
Rinse your spinach in a colander then pour a kettleful of boiling water over it to wilt it. Rinse with cold water to refresh, then squeeze as much water out as you can. Chop and add to the bowl.
Next add the seeds, oats, spices, garlic and black pepper and mix until well combined.
Shape your mixture into 4 hearty balls, then flatten out into burger shapes.
Pop the burgers on a plate until you are ready to use them. You can bake or fry them in a little oil. I fried my burger in a little cold pressed rapeseed oil, for a few minutes on each side until brown and crisp.
These burgers will also freeze well.
Layer them between sheets of greaseproof paper in a tupperware tub and pop in the freezer.
