Peel and finely chop the onion. Heat the fat in a pot and fry half of the onion cubes in it until transparent. Pour on 1/2 litre of water, add the herbs and bring to the boil. Add rice flakes and cook for about 1 minute while stirring.
Swell over low heat for 10-15 minutes and let cool. In the meantime wash and clean the zucchini and cut them into fine cubes. Heat oil in a pot and fry the remaining onions and diced courgettes.
Season with salt and pepper and add chunky tomatoes. Boil up the vegetables, let them boil down for about 5 minutes and season with salt and pepper. Stir eggs into the rice mixture. Heat some clarified butter in a large pan and bake about 12 golden brown rice buffers in portions.
Arrange on plates with zucchini-tomato vegetables and sprinkle with fresh thyme and serve garnished with parsley.
