Dish king and infant returned (5)
I believe the answer is:
kebab
'dish' is the definition.
(kebab is a kind of dish)
'king and infant returned' is the wordplay.
'king' becomes 'k' (abbreviation for king in chess).
'and' is a charade indicator (letters next to each other).
'infant' becomes 'babe' (synonyms).
'returned' says the letters should be written backwards.
'babe' back-to-front is 'ebab'.
'k'+'ebab'='KEBAB'
(Other definitions for kebab that I've seen before include "Brochette" , "Grilled or roasted dish; b-bake (anag.)" , "Small pieces of meat and vegetables cooked on skewer" , "Meat grilled on skewer" , "Meat and/or vegetables cooked on skewer" .)
