Meet the members of the Wellington Family, foods related in spirit and structure to Beef Wellington: pigs in a blanket, Hot Pockets, corn dogs, and Pop Tarts.
See also The Cube Rule of Food, which suggests that the Wellington Family actually belongs to the larger Calzone Clan but sadly that pigs in a blanket are actually sushi.
P.S. I found this illustration here but couldn't trace the original source. Happy to give credit is anyone knows where this is from...
Update: The creator of the Wellington Family illustration is Jade Robin of Otter Mage Designs. (thx, ben)
