Praise pet that's chewed a tasty morsel (9)
I believe the answer is:
appetiser
'a tasty morsel' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'praise pet that's chewed' is the wordplay.
'that's chewed' indicates an anagram.
'praise'+'pet'='praisepet'
'praisepet' anagrammed gives 'APPETISER'.
Can you help me to learn more?
(Other definitions for appetiser that I've seen before include "It's served before a meal" , "Hors d'oeuvre" , "Antipasto" , "stimulating food!" , "preprandial treat" .)
