Missing centrepiece of meals, hurried for a big shop (10)
I believe the answer is:
superstore
'a big shop' is the definition.
(a superstore is a large shop)
'missing centrepiece of meals hurried' is the wordplay.
'missing centrepiece of' means to remove the middle letters.
'meals' becomes 'suppers' (supper is a type of meal).
'hurried' becomes 'tore' (tear can mean to rush or hurry).
'suppers' with its centre taken out is 'supers'.
'supers'+'tore'='SUPERSTORE'
'for' acts as a link.
(Other definitions for superstore that I've seen before include "Retailer" , "Large out-of-town shop" .)
