Add the rice paper to a dry pan over low heat. Add the lightly beaten egg on top, spreading it out to the edges.
Top with green onions and protein of choice. Let the egg cook and the rice paper crisp, moving the rice paper around if crisping unevenly.
When crispy and crunchy, finish with mayo and hot sauce to taste. Enjoy open or fold it up like they do in Vietnam. Enjoy hot!
