Briefly whisk together egg whites in a small bowl.
Lightly oil a small non-stick pan (or don't if your pan is really non-stick) and heat it over medium- low.
Add the egg whites to the pan and season with salt and pepper.
As the egg whites begin to cook, tilt the pan in a circular motion to move uncooked egg to the edges of the pan.
If you have trouble getting egg to move using the method above, use a silicone spatula to lightly pull the edges closer to the center, then tilt the pan.
When egg whites are set on the bottom and there is only a thin layer of uncooked egg on the top, add all veggies, herbs, and cheese choices over the egg whites.
Use a spatula to carefully fold the egg white in half, over the filling.
Cook for 30 seconds, then flip, and cook for 30 seconds longer.
Eat your egg white omelet as is or pair it with your favorite salsa or hot sauce.
