Place your bread in your toaster. Meanwhile, open up the avocado, take the pit out and mash it in a bowl. Add cream cheese if using, and mix together with avocado until smooth.
Spray a medium/small skillet with cooking spray. Place it over medium heat and carefully crack eggs into pan. Let eggs cook for 3-4 minutes or until the whites have cooked through.
Once the toast is done, spread mashed avocado on it. Add the everything bagel seasoning, and one egg on top of each piece of toast and tomatoes if using. Add salt and pepper to taste. Enjoy warm!
