On the now defunct cartoon "Futurama," Bachelor chow is the substance that the main character Phillip J. Fry eats with regularity. It comes in a large bag akin to Dog Chow and makes its own gravy when you add water. The bag advertises that Bachelor Chow is "Now with flavor!"
Food that is easily prepared, has enough vitimins and minerals to preserve life, and cheap to buy.
Cause most single guys living alone are poor and/or lazy but still need to survive.
A great example of bachelor chow is cerial, $4 buys you 5-8 meals..just add milk..or not.
Also KD and hot dogs among many others.
