Preheat the oven to 350 degrees F. Spray a 9x13” baking dish with nonstick cooking spray.
Open crescent rolls and place along the bottom of the dish. Press down to spread and even out along the bottom and part of the sides of the dish. Try to seal the seams as much as possible.
Shake egg white carton up and pour slowly over the crescent roll dough. Sprinkle with Italian seasoning and salt and mix to spread evenly.
Bake for 18-20 minutes, or until egg whites are cooked throughout. Take out and sprinkle with mozzarella and feta cheese. Top with sun dried tomatoes, red onions and fresh spinach.
Bake for 5-7 minutes or until the cheese has melted. Take out, let cool for 5-10 minutes and enjoy!
