Meat it's a relief to save (5)
I believe the answer is:
bacon
'meat' is the definition.
(bacon is a kind of meat)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for bacon that I've seen before include "gammon" , "Man killed by chicken, some say" , "Meat (that's brought home?)" , "Meat - essayist - painter" , "Writer of essays" .)
