Potatoes partner (4)
I believe the answer is:
meat
'potatoes partner' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for meat that I've seen before include "grub, say" , "Chops, steaks etc" , "Eg, beef or pork" , "Animal flesh as food" , "Spam, ham, lamb etc" .)
