Rinse the beans in a colander and set aside a quarter of them in a bowl to add later, then pour the rest into a large bowl.
Mash the beans with a potato masher until you have a paste then add the herbs, spices, oats and whole beans to the bowl and mix with a spoon until well combined.
Shape the mixture into 6-8 balls using your hands and then squash them into burger shapes.
These are now ready to cook. Heat a frying pan with a little olive oil and fry each side for a few minutes until crisp and starting to brown. You could also bake these on a baking tray in a hot oven for 20-25 minutes.
