Grate zucchini and potatoes on a box grater. Using your hands or a towel, squeeze out the liquid.

To the grated vegetables, add eggs, salt, and pepper. Mix together. Add matzo meal and mix until homogeneous.

Use a well-sprayed donut pan to form donut shapes from the latke batter. Carefully transfer out by flipping onto a second tray. Heat a frying with a small amount of vegetable oil. Fry donut-latkes on both sides until golden brown.

Serve with sour cream or cottage.
