Crack eggs and separate the whites into a bowl. Measure about half a cup, then sprinkle in the xanthan gum. Whisk together until smooth and a little thicker.
Heat non-stick skillet over medium heat. Optionally grease lightly if necessary.
Pour a thin layer of egg white mixture into skillet, spreading evenly into a round crepe shape.
Cook for 2 to 3 minutes until edges lift and surface looks set but not dry.
Flip carefully with spatula and cook for another 1 to 2 minutes until fully set but still soft and bendy.
Slide wrap onto plate and repeat with remaining mixture.
Fill wraps with desired ingredients and serve warm or store for later.
Notes
Optional fillings can include cheese, veggies, or meats. Store wraps airtight in fridge for 2-3 days or freeze for up to 1 month.
