Pips ran out of food (7)
I believe the answer is:
parsnip
'food' is the definition.
(parsnip is a kind of food)
'pips ran out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'pips'+'ran'='pipsran'
'pipsran' is an anagram of 'PARSNIP'.
'of' acts as a link.
(Other definitions for parsnip that I've seen before include "Yellow root vegetable" , "Pips ran oddly through the vegetable" , "Tapering vegetable" , "Pale carrot-like vegetable" , "Plant with edible white root" .)
