1. Heat a nonstick pan over medium-high heat and spray with cooking spray. Add apple slices, rosemary, and a pinch of salt and pepper. Cook for 4-5 minutes, until apples are browned and tender. Remove apples from pan and set aside.
2. Add eggs to pan and tilt to coat the bottom of the pan. Cook for 2-3 minutes, until eggs are starting to set.
3. Top with apples and cheddar cheese. Continue cooking until cheese is melted and the eggs are fully set. Fold in half and serve with whole grain toast.
