- Shred the zucchini through the large holes of a grater. Transfer to a strainer on top of a bowl and toss with the salt and let sit for 10-30 minutes. 
- Wring out the zucchini shreds, either by hand or by putting handfuls into the center of a clean dishtowel and twisting the towel. Try to get out as much water as possible. 
- Finely mince the onion or shred it with the grater. Mince the fresh dill and the garlic. 
- Beat the eggs in a large bowl. 
- Heat a large skillet on medium heat and add a little bit of oil. 
- Mix in the zucchini, the feta cheese, the onions or scallions, the dill, the garlic and the pepper. Mix. 
- Sprinkle and mix in the baking powder and flour until well combined. 
- Drop large spoonfuls of the batter onto the skillet, but do not crowd them together. Lightly press down on the fritters with the back of a spoon. 
- Turn when golden brown, about three minutes. After the other side is golden brown, remove to a plate and serve with tzatziki and hummus.
