Grate the zucchini in a medium bowl.

Add egg whites to the grated zucchini and mix well.

Incorporate cottage cheese, diced onion, rice flour (or all-purpose flour), wheat germ (optional), salt, and pepper into the mixture.

Stir until all ingredients are thoroughly combined.

If a firmer patty consistency is desired, add additional flour to thicken the batter.

Lightly coat a pan with cooking spray or olive oil and heat over medium heat.

Drop batter by the tablespoon onto the hot pan, spreading slightly to resemble a pancake.

Cook covered for 3-4 minutes, or until the top starts to set.

Flip the patties and cook uncovered for approximately 5 minutes, or until golden brown.

Serve hot.
