Heat 1/4" canola oil in pan on medium heat.
Slice zucchini in 1/4" slices and set aside.
Place flour, beaten egg, and breading mixture in 3 separate bowls.
For the breading: combine breadcrumbs, parmesan, salt, pepper, garlic powder, onion powder.
To bread zucchini slices, dredge each slice in flour (shake off excess), then dunk in beaten egg, then into breadcrumbs. Press firmly to make sure breadcrumbs stick to the slice.
Once oil is heated, cook each zucchini slice for approximately 1 minute on each side or until golden brown.
Remove from oil and drain on paper towel before serving with your favorite dipping sauce.
