These are some very good videos to accompany the Salmon Teriyaki meal plan for a bento box featuring Sushi with real crab with a choice of sides and soup.

Crab Rangoon
Image of crab rangoon I have no recipe for crab Rangoon as it is not vegan.
Although, I could probably make it with a minced parsnip salad and vegan cream cheese.
However, if you have left over bits of crab, this would be  great and easy appetizer to make. I spray my finished wontons with avocado spray and bake them for about 15 minutes until they are crisp. This page has a recipe and instructions.
