Line a baking sheet with paper towels. Lay zucchini slices flat in a single layer onto the prepared baking sheet. Season with salt, to taste; let stand 15 minutes.
In a large bowl, combine Panko and Parmesan; set aside.
Working in batches, dredge zucchini rounds in flour, dip into eggs, then dredge in Panko mixture, pressing to coat.
Add zucchini rounds to the skillet, 5 or 6 at a time, and cook until evenly golden and crispy, about 1 minute on each side. Transfer to a paper towel-lined plate.
Serve immediately.
Notes
*Panko is a Japanese-style breadcrumb and can be found in the Asian section of your local grocery store.
