Beat the egg whites, vanilla and sweetener until stiff and fluffy.
Spread onto a parchment-lined baking sheet, sprinkle with a little cinnamon and salt, and bake at 400°F for 8-10 min, until set and lightly golden.
Mix the light cream cheese, Greek yogurt, vanilla and powdered monk fruit until smooth.
Spread the filling over the baked egg-white sheet, then gently roll it up.
Finish with cinnamon and an extra dusting of powdered sweetener to taste.
