Prepare the Vegetables: Grate the zucchini, carrot, and potato. Place them in a bowl and sprinkle with salt. Let the zucchini sit for 10 minutes to release excess moisture. After 10 minutes, squeeze out the liquid.

Combine Ingredients: In a mixing bowl, combine the grated zucchini, carrot, potato, and minced garlic.

Add the grated cheese, eggs, oat flakes, flour, and your chosen spices. Mix well until everything is combined.

Shape the Fritters: Take a small amount of the mixture and shape it into a log or roll. Repeat until all the mixture is shaped into fritters.

Fry the Fritters: Heat olive oil in a frying pan over medium heat. Once hot, carefully place the fritters in the pan.

Fry for about 4-7 minutes on each side or until golden brown and crispy.

Prepare the Topping: In a small bowl, mix the sour cream and mayonnaise together. Set aside.

Serve: Serve the fritters warm, topped with the sour cream and mayonnaise mixture, and garnish with fresh cucumber slices on the side.
