Cut the onions into small pieces and sauté them in the oil until they are translucent, then season with the paprika powder. Add the feet to the onions and fold in. Add enough vegetable stock until everything is almost covered, season with the spices and then simmer for 30 to 40 minutes until the juice thickens. If necessary, pour in the broth more often and turn the feet. Be careful not to burn anything. When the meat separates from the bone, the dish is ready.
Alternatively, you can prepare it in a pressure cooker by cooking the feet with the vegetable stock for 20 minutes. In the meantime, cook the onions as described above, then mix the onions and feet and cover everything with the stock. Boil the feet until the meat separates from the bone.
