Remove kale leaves from 2 stalks, massage leaves by rubbing between hands to soften them. Rip up or chop into bite sized pieces. Chop ½ apple into bite sized pieces. Set aside.
Add 1 tablespoon milk and salt/pepper to eggs, whisk together until mixture is smooth.
Spray hot pan with cooking spray, then pour egg mixture into pan. Once eggs have began to cook, cover egg mixture evenly with kale, apple, and cheese. Cook until eggs are cooked through and cheese is melted.
Fold egg mixture over. Serve immediately
Use a really crisp apple like honeycrisp, braeburn, or a crisp fuji apple.
Don't feel bad if you break your omelette when folding it. It's easy when you've got lots of goodies inside it.
Want to take it up a level? Sautee the kale and apples in some butter before cooking the eggs.
