Dish, second, our people welcome (5)

I believe the answer is:
sushi
'dish' is the definition.
(sushi is a kind of dish)
'second our people welcome' is the wordplay.
'second' becomes 's' (common abbreviation).
'our people' becomes 'us' (us refers to 'our' group or our people).
'welcome' becomes 'hi' (both are greetings).
's'+'us'+'hi'='SUSHI'
(Other definitions for sushi that I've seen before include "fare from Japan" , "Japanese food" , "Asian dish" , "Food from Japan" , "Japanese rice and raw fish dish" .)
