This recipe combines spinach, nuts, eggs, rice, onion, sunflower seeds and cheddar cheese.
In a food processor, grind the nuts until they are fine, with the consistency of coarse flour. Combine with all the other ingredients and mix thoroughly. Shape into 6 to 8 burgers. Cook in a lightly greased frying pan until brown, letting them cook at least 10 minutes on the first side so that they hold together when you turn them over. Serve as you would hamburgers.
