Providing revolutionary service for meat dish (5)
I believe the answer is:
filet
'for meat dish' is the definition.
(French spelling of fillet)
'providing revolutionary service' is the wordplay.
'providing' becomes 'if' (eg 'providing it's sunny' means 'if it's sunny').
'revolutionary' says the letters should be written backwards (letters revolve around).
'service' becomes 'let' (type of tennis serve).
'if' in reverse letter order is 'fi'.
'fi'+'let'='FILET'
(Other definitions for filet that I've seen before include "French cut of beef" , "Beef undercut" , "Boneless tender steak in France" , "French-style piece of meat" .)
