Cooked meats provide energy (5)
I believe the answer is:
steam
'energy' is the definition.
(I've seen this before)
'cooked meats' is the wordplay.
'cooked' is an anagram indicator (letters cooked into a new form).
'meats' is an anagram of 'STEAM'.
'provide' is the link.
(Other definitions for steam that I've seen before include "Invisible gas from boiling water" , "fume" , "comes with a hiss?" , "Sort of water" , "Kind of power" .)
