Here's my dad's recipe. Shred zucchini into a bowl. Let it stand 1/2 hour then drain excess water. Add 1 egg, flour, mint and salt/pepper. Use enough flour to make it pancake like batter. More egg for more batter. Probably about 2 tablespoons of mint to start.
Heat olive oil in skillet then add batter and grill. Flip after brown on one side. Can be messy and tough to get the right consistency but always tastes great.
