Preheat oven to 400 degrees. Prepare a baking sheet with a silicone mat.
In a medium bowl, beat egg whites and sugar until fluffy. Add the rest of the ingredients and blend until smooth.
Drop a teaspoon of the batter on prepared baking sheet and spread to a thin 3 inch by 7 inch rectangle using an offset spatula. Bake for 4 to 6 minutes or until the edges just start to brown. Quickly roll the cookie onto a straw or skewer and lay seam-side down until cool.
