Cut the zucchini and squash into thirds and then each section into fry sized cuts.
On one plate, crack the eggs and whisk them up. On another plate, mix together the bread crumbs, parmesan and salt.
Place the air fryer grate in the tray and spray it quickly with oil spray.
Take a piece of zucchini, dip it in the egg then coat in the breadcrumbs and place on the air frying sheet. Repeat with all the zucchini and squash, leaving a little space in between each piece.
Spray lightly with oil spray and air fry for 10-12 minutes, flipping halfway through.
Serve when golden brown.
