Steak main course absorbing company time (9)
I believe the answer is:
entrecote
'steak' is the definition.
(I've seen this before)
'main course absorbing company time' is the wordplay.
'main course' becomes 'entree' ('entree' can be a synonym of 'main course').
'absorbing' indicates putting letters inside.
'company' becomes 'co' (abbreviation).
'time' becomes 't'.
'co'+'t'='cot'
'entree' going around 'cot' is 'ENTRECOTE'.
(Other definitions for entrecote that I've seen before include "Piece of meat" , "Boned steak cut off the sirloin" , "a good cut" , "Steak cut from between the ribs" .)
