Place grated zucchini in a colander, sprinkle with salt and let stand at least 20 minutes, or until it loses its juice. Squeeze dry and place in a large bowl. Add the cheese, dill, parsley, onions, eggs, flour, and pepper and mix well. Adjust the seasonings. If batter is too runny, add a little more flour.
Heat oil in a heavy saucepan. Drop batter by tablespoons into oil and fry until golden brown on all sides but still moist inside, about 2 to 3 minutes. Drain on paper towels and serve warm with Tomato Relish.
Combine all the ingredients in a bowl and mix well. Taste for seasoning. Set aside at room temperature for a few hours, or cover and chill for several days.
