With paper towel, squeeze dry the zucchinis and place in a bowl. Add almond flour, green onions, Parmesan, and egg. Season with pepper and salt. Whisk well to combine.

Place a large nonstick pan on medium fire and add oil to cover pan. Once hot, add ¼ cup of zucchini mixture and shape into a square like a bread. Add another batch as many as you can put in the pan. If needed, cook in batches. Cook for four minutes per side and place on a paper towel lined plate.

Once done cooking zucchinis, wipe off oil from the pan. Place one zucchini piece on pan, spread ½ of shredded cheese, and then top with another piece of zucchini. Grill for two minutes per side. Repeat process to make 2 sandwiches.

Serve and enjoy.
