This is traditionally made over a grill, but since I don't have that, I'm using a pan or a griddle. Over medium heat (350 F), add the dry rice paper and allow to crisp.
Melt vegan margarine on top, then add your vegan egg alternative.
Quickly add diced green onions, and mix well to coat the rice paper in a thin even layer.
Add slivered vegan ham or hotdog and vegan cheese, and let that melt for a minute or so. You can leave this "open" like a pizza, and top with vegan kewpie mayo or Vietnamese chili sauce, or fold in half, then top with mayo and chili sauce.
Enjoy hot! Traditionally served with a piece of newspaper to hold the hot folded "pizza".
