Be idle, perhaps, with something to eat? (6)
I believe the answer is:
edible
'something to eat?' is the definition.
(edible is a kind of food)
'be idle perhaps' is the wordplay.
'perhaps' indicates an anagram.
'be'+'idle'='beidle'
'beidle' with letters rearranged gives 'EDIBLE'.
'with' is the link.
(Other definitions for edible that I've seen before include "Fit for eating" , "Fit to consume" , "Esculent" , "Fit to be used as food" , "Fit to eat" .)
