Disembowel wild pig, lubricate and cook (5)
I believe the answer is:
broil
'cook' is the definition.
(I know that broil is a more specific form of the action grill)
'disembowel wild pig lubricate' is the wordplay.
'disembowel' says to hollow out the word (remove centre letters) (I've seen 'disembowelled' mean this).
'wild pig' becomes 'boar' (I've seen this before).
'lubricate' becomes 'oil' (synonyms).
'boar' with its centre taken out is 'br'.
'br'+'oil'='BROIL'
'and' is the link.
(Other definitions for broil that I've seen before include "cook?" , "American heat" , "disturbance" , "get very heated" , "stew" .)
