A stupid amount of Chinese food? (3,3)
I believe the answer is:
dim sum
'chinese food?' is the definition.
(I've seen this before)
'a stupid amount' is the wordplay.
'a stupid' becomes 'dim' (I've seen this before).
'amount' becomes 'sum' ('sum' can be a synonym of 'amount').
'dim'+'sum'='DIM SUM'
'of' acts as a link.
(Other definitions for dim sum that I've seen before include "Chinese course" , "Chinese meal, a variety of dishes served in small portions" , "something to take away?" , "Asian food" , "fare from China" .)
