Place your thinly sliced zucchini in a bowl, lightly salting them as you layer them in the bowl and add more. Cover and refrigerate over night.
Remove the zucchini from the bowl, a few at a time, and squeeze out the excess water as you go, the same way you would squeeze water from a sponge.
In a large bowl whisk the eggs. Then mix in the flour, milk, garlic salt, and pepper. Finally stir in the cheese.
Heat a skillet over low to medium heat.
Add about five zucchini slices to the batter. Coat them completely and pull them out with a fork.
Spray the skillet with cooking spray and cook the zucchini slices for about two minutes on each side. Repeat with more zucchini, adding more cooking spray as needed.
These are best when eatten while warm.
