Grate the onion and garlic using a grater and put them in a bowl. I use the coarse side for the onion and the fine side for the garlic. Also, grate the carrot and zucchini and add to the bowl. Chop the parsley and add to the bowl.
Add eggs, flour, breadcrumbs, and spices and mix well with the vegetables.
Drain the couscous and mix with the other ingredients.
Form the patties and fry them in a pan with a little butter.
