In a medium bowl, whisk the 8 large egg whites until slightly frothy and set aside.
Heat 1 tablespoon of olive oil in a non-stick skillet over medium heat.
Add 1 cup of sliced mushrooms to the skillet and sauté for 2-3 minutes until they begin to soften.
Add 2 cups of fresh spinach to the mushrooms and cook for another 1-2 minutes, stirring, until the spinach is wilted.
Pour the whisked egg whites evenly over the spinach and mushrooms in the skillet.
Cook the egg whites undisturbed for 2-3 minutes, or until they begin to set around the edges.
Sprinkle 1 ounce of feta cheese evenly over the omelette.
Using a spatula, gently fold the omelette in half and cook for another 1-2 minutes until the egg whites are fully set and the cheese is slightly melted.
Slide the omelette onto a plate and serve immediately.
