Leave, and hauls away a dish (7)
I believe the answer is:
goulash
'a dish' is the definition.
(goulash is a kind of dish)
'leave and hauls away' is the wordplay.
'leave' becomes 'go' (to go is to depart or leave).
'and' means one lot of letters go next to another.
'away' is an anagram indicator (letters move away from their original places).
'hauls' is an anagram of 'ulash'.
'go'+'ulash'='GOULASH'
(Other definitions for goulash that I've seen before include "Rich stew of Hungarian origin" , "Hungarian stew of meat and veg with seasoning" , "food" , "Rich stew from Hungary" , "Stew of meat and veg, seasoned with paprika" .)
