Grate the zucchini with the coarse side of a grater, skin on. Sprinkle with ½ teaspoon salt, mix, and set aside.
Grate the carrots the same way. Sprinkle with ½ teaspoon salt, mix, and set aside.
Squeeze the zucchini by hand to remove as much water as possible. Transfer to a large bowl.
Do the same for the carrots and add them to the zucchini.
Add finely chopped red pepper and dill.
Crack in the eggs and mix well.
Add flour, baking powder, and salt. Mix until combined.
Crumble in the feta cheese and stir everything together.
Heat sunflower oil in a pan over medium heat.
Test the oil: if a pinch of flour sizzles nicely, it’s ready.
Drop a tablespoon of the mixture into the hot oil. Gently flatten each one with the back of the spoon.
Fry 4-5 fritters at a time (depending on pan size) without crowding.
Cook for about 3 minutes, flip, and fry the other side until golden (2–3 minutes).
Transfer to a paper towel-lined plate to absorb excess oil.
Repeat until all the mixture is used.
