Grub with rice all part boiled (11)
I believe the answer is:
caterpillar
'grub' is the definition.
(thesaurus)
'rice all part boiled' is the wordplay.
'boiled' indicates anagramming the letters.
'rice'+'all'+'part'='riceallpart'
'riceallpart' is an anagram of 'CATERPILLAR'.
'with' is the link.
(Other definitions for caterpillar that I've seen before include "Track" , "future monarch, perhaps" , "Butterfly grub" , "looper, perhaps" , "Lepidopteran larva" .)
