Spray skillet with cooking spray and heat over medium. Chop broccoli into smaller pieces; peel and shred carrot.

Whisk eggs and egg whites together in a medium-sized bowl; pour into hot skillet. Add broccoli and carrots, stirring frequently to combine and scramble.

When eggs are no longer runny, add spinach and cheese. Cook for 1-2 minutes longer until spinach is wilted and cheese is melted.

Serve with apple slices on the side.
