Grate the zucchinis into a large bowl, add in the finely chopped tomatoes, onion, mint, parsley and salt.
Stir together to combine, but also draw out some of the liquid from the tomatoes thanks to the salt.
Place the flour and baking powder into a separate bowl and stir together.
Toss into the tomato mixture and stir until no dry portions remain in the base or edges of the bowl and your batter has formed.
The mixture should hold lightly on a tablespoon without running off, if it does, add a tablespoon of flour at a time until it does. This is dependent on the amount of liquid in your tomatoes.
Place enough oil into a small pot to come 3 inches up the side and heat on medium high.
Shape a tablespoonful of batter and slide on a square of baking paper, turning onto your hot oil.
Reduce the heat to medium low and cook for 2-3 minutes on one side until deep golden in color.
Flip and cook the remaining side until deep golden also, turning the temperature up to cook the fritters in the first minute before reducing the heat one more.
Remove with a slotted spoon and place onto a draining tray.
Continue with the remaining batter until completely cooked, not crowding the pot with too many fritters (2 large and medium were ideal in my pot).
Serve up, these work well with some tzatziki to dip into. Enjoy!
