“What is the preferred sandwich of the working class?”/“A plebian-J.”

A peanut butter and jelly sandwich is called “PB&J,” and this sounds like “plebeian/plebian J.” A riddle was posted on Twitter on June 30, 2010:
 
Q: What is the favorite sandwich of the proletariat?
A: A plebian J.
 
     
Wikipedia: Peanut butter and jelly sandwich
A peanut butter and jelly sandwich, or PB&J, includes one or more layers of peanut butter and one or more layers of either jelly or jam on bread. Sometimes the sandwich is eaten open-faced or with one slice of bread folded over (effectively a “half sandwich”). If the peanut butter is not spread on each slice of bread, the sandwich will become soggy if it’s left too long to sit.
