Piece of meat in one basket put out next to back of supermarket (1-4,5)

'piece of meat' is the definition.
'T-bone steak' can be an answer for 'meat' (T-bone steak is an example). I am not certain of the 'piece of' bit.

'one basket put out next to back of supermarket' is the wordplay.
'put out' is an anagram indicator.
'next to' means one lot of letters go next to another.
'back of' indicates one should take the final letters.
The final letter of 'supermarket' is 't'.
'one'+'basket'='onebasket'
'onebasket' is an anagram of 'bonesteak'.
'bonesteak' put after 't' is 'T-BONE STEAK'.

'in' is the link.
