Line a mixing bowl with paper towels and grate the zucchini with a cheese grater. Lightly season with salt.
Transfer the grated zucchini into a tea towel or cheesecloth and squeeze out as much of the liquid as possible. Return to the bowl and add the hard cheese, eggs, almond flour, and a pinch of salt and pepper.
Set aside for a couple of minutes so that the almond flour will soak up any remaining moisture.
Heat the olive oil in a frying pan and add dollops of the zucchini mixture to make the fritters.
Cook for 2-3 minutes on each side and serve hot, topped with mayonnaise and chopped fresh herbs such as parsley or dill.
