Preheat oven to 350 degrees. Lightly coat a baking sheet with cooking spray.
Toss yellow squash with light extra virgin olive oil in a medium mixing bowl.
In a small mixing bowl, combine fin seas salt, ground black pepper, garlic powder, onion powder, Parmesan cheese and bread crumbs.
Arrange yellow squash in a single layer on prepared baking sheet. Spoon bread crumb mixture evenly over each squash round, pressing down lightly on each one.
Bake for 15 minutes, or until squash is soft, but not mushy.
