Put grated zucchini and chopped tomato into a colander of mesh strainer placed over a bowl and sprinkle 1 tsp salt over them. Stir and let sit for about 30 minutes.
Transfer zucchini mixture to a mesh bag, cheese cloth, or kitchen towel. Wrap, hold over the sink or a bowl, and squeeze tightly to extract as much water as you can. If preferred, you can just use your hands to squeeze water out.
In a large bowl, add grated zucchini, chopped tomato, scallions, feta, panko, oregano, parsley, basil, red pepper flakes, remaining ¼ tsp salt, pepper, garlic, and egg. Mix together until well combined.
Using your hands, form about 10 patties with the mixture.
Heat a large skillet over medium heat. Add 2 Tbsp olive oil and when hot, place half the zucchini cakes in skillet. Cook for 3-5 minutes per side, until cakes are golden brown.
Serve zucchini cakes topped with Tribe Mezze Dip of your choice (I highly recommend the Spicy Tomato Feta Dip) and chopped parsley.
