Cold dish fellow included with hesitation for amphibian (10)
I believe the answer is:
salamander
'for amphibian' is the definition.
(salamander is a kind of amphibian)
'cold dish fellow included with hesitation' is the wordplay.
'cold dish' becomes 'salad' (meal served cold).
'fellow' becomes 'man' (fellow can mean a man).
'included' is an insertion indicator.
'with' is a charade indicator (letters next to each other).
'hesitation' becomes 'er' (sound used when hesitating).
'salad' going around 'man' is 'salamand'.
'salamand'+'er'='SALAMANDER'
(Other definitions for salamander that I've seen before include "amphibious creature" , "Beast" , "Long-tailed amphibian" , "An amphibian; fire spirit" , "Newt-like amphibian" .)
