Wash the zucchini and greens. Peel the onion; if the zucchini is old, cut off the rough skin.
Pour boiling water over oatmeal and leave for 10 minutes. Grate the zucchini on a coarse grater, add salt and drain the liquid after 3 minutes. Finely chop the onion and herbs (dill, parsley, cilantro).
Mix all ingredients, oatmeal, zucchini, onion, herbs, egg, salt. Heat a frying pan over medium heat, spoon in the pancakes and fry them for 5 minutes on each side.
Serve the zucchini pancakes with sour cream sauce; you can add chopped herbs or garlic to it.
