In a plate, mix the matza meal, za'atar mix, salt and peper. In a separate bowl, whisk the egg and water.
Place the fish in the egg mixture and mix until the fish is thoroughly coated and then dip in the matza meal mixture until well coated. Cook the fish in about 25mm (1 inch) of hot oil for approximately two to three minutes on each side or until flaky. Drain on a paper towel and serve immediately.
