Spinach Tomato and Feta Egg White Omelet

Place a skillet over medium-high heat and spray with nonstick cooking spray.

Saute spinach and tomatoes until spinach has wilted.

Pour egg whites into the skillet, tilt to cover the bottom of the pan in an even layer and cover with a lid for 3-5 minutes, or until eggs are set.

Remove lid and sprinkle feta on top of the omelet.

Use a rubber spatula to lift the edges of the omelet and fold in half.

Carefully slide the omelet onto a plate and serve.
