Slice onions horizontally (forming cirlcles) to desired thickness.

In bowl, lightly whisk egg with milk and set aside.

In separate bowls for each, add the flour and breadcrumbs. Season both with a little salt and pepper.

Dredge onions in flour first, then egg mixture, then panko crumbs.

Wipe olive oil (with a brush or paper towel) on baking sheet. Arrange breaded onions on same sheet and spray with olive oil cooking spray.

Bake at 385 F (or a little higher) for 10 minutes. Flip and bake for another 10 minutes until golden brown.

Enjoy as is or dip in your favorite condiment!
