Line a baking sheet with foil, spray well with cooking spray and set aside.

Preheat oven to 400F.

Core and slice the apples into 8 slices each.

Place the Cheerios into a zipper bag and roll with a rolling pin or tap with the back of a spoon until broken up but not completely crushed.

One at a time, lightly brush the yogurt onto an apple slice with a pastry/rubber brush, roll it into the cereal and place on the baking sheet. You will have yogurt leftover.

Repeat for each slice. Spray the tops with more cooking spray.

Bake for 5 minutes.

Remove from oven and let cool for a few minutes, serve immediately.
