Alan Cook drop in for some Italian food? (7)
I believe the answer is:
lasagna
'some italian food?' is the definition.
(I've seen this before)
'alan cook drop in' is the wordplay.
'cook' indicates anagramming the letters.
'drop' becomes 'sag' (sagging is a kind of dropping).
'in' indicates putting letters inside.
'alan' with letters rearranged gives 'lana'.
'lana' going around 'sag' is 'LASAGNA'.
'for' acts as a link.
(Other definitions for lasagna that I've seen before include "Broad flat pasta" , "Italian dish" , "Calorie-rich food" , "Baked pasta dish" , "Italian food" .)
