Do not peel the zucchini. Simply cut off the stem end and shred the squash on a box grater or run through the shredder attachment on your food processor. To squeeze out the excess liquid you press it into a colander, allowing the juice to flow out, or use a cheesecloth. Place shredded, drained zucchini in a large mixing bowl.
Beat the eggs in a medium mixing bowl, adding half of the flour and beating again. Add lemon pepper and garlic salt and beat together.
Add egg mixture, remaining flour, panko breadcrumbs, green onion, and garlic to the zucchini. Use gloved hands to combine the mixture.
Form mixture into six equal patties and place on a metal baking sheet. Refrigerate for 30-60 minutes to firm them up.
In a large skillet over medium-high heat, bring oil to 350 F.
Add fritters, 2 or 3 at a time, to hot oil in the skillet, being careful not to crowd them. Cook for 3-5 minutes, or until nicely browned, then turn over. Cook an additional 3-5 minutes, or until nicely browned.
