Grub

I heard a word in a cop show the other nite--"...by the way, thanks for the grub."--referring to a just finished meal in a restaurant.
Anybody know the origin of "grub"?

There is a Middle English word "grubben" and Old English "grafan" meaning "to dig" which can be linked to the word "grave" as in final resting place.

Webster's has grub as a verb as "to dig in the ground especially for something that is difficult to find or extract"--so could "grub" be digging around in the dirt for a potato or carrot?

Anybody?
thanx

"Whistlin' Dixie" by Robert Hendrickson has "GRUB UP -- To dig out. 'I been grubbing up a clump of willows outen my spring pasture for fifteen years.' (William Faulkner, 'The Hamlet' 1940)
