Season and turn Chinese snack (6,4)
I believe the answer is:
spring roll
'chinese snack' is the definition.
(I've seen this before)
'season and turn' is the wordplay.
'season' becomes 'spring' (spring is a season).
'and' says to put letters next to each other.
'turn' becomes 'roll' (rolling is a kind of turning).
'spring'+'roll'='SPRING ROLL'
(Other definitions for spring roll that I've seen before include "Chinese snack" , "Chinese pancake" , "Gloucestershire event?" , "dish from China" , "Portion of Chinese food" .)
