Brother tucks into chopped salami — it's delicious (9)
I believe the answer is:
ambrosial
'delicious' is the definition.
(thesaurus)
'brother tucks into chopped salami' is the wordplay.
'brother' becomes 'bro'.
'tucks into' is an insertion indicator.
'chopped' is an anagram indicator.
'salami' anagrammed gives 'amsial'.
'bro' inserted inside 'amsial' is 'AMBROSIAL'.
'it's' acts as a link.
(Other definitions for ambrosial that I've seen before include "Delightful" , "Heavenly" , "Divine" , "Like special food" , "delicious" .)
