Take in food - trimmed meats? (3)
I believe the answer is:
'take in food' is the definition.
'trimmed meats?' is the wordplay.
'trimmed' indicates the central letters (the edge letters are trimmed off).
The middle of 'meats' is 'EAT'.
(Other definitions for eat that I've seen before include "Gobble up" , "Partake of" , "Make food disappear" , "put away" , "Scoff" .)
