Halve the zucchinis then lengthwise cut them into 4 vertically and horizontally so we'll have 8 slices.
Sprinkle salt and mix it well with the zucchini. Let it sit for about 15 minutes.
Whisk the egg and dunk the zucchini slices into the egg.
Let the zucchinis drip off excess egg before proceeding to the cheesing.
Roll the egged zucchinis into the grated cheese lightly.
Place the zucchinis onto a parchment papered baking tray. We can place them fairly close to each other as they won't grow in size.
We can opt for the less streneous method of carelessly mixing everything together and dumping the whole thing onto the parchment layered baking tray but the results will be linear to the invested efforts.
Bake the zucchinis in a 400°F / 200°C oven until the cheese gets golden brown spots for about 30 minutes.
