Lame arrangement for lunch, say (4)
I believe the answer is:
meal
'for lunch say' is the definition.
(lunch is a kind of meal)
'lame arrangement' is the wordplay.
'arrangement' indicates an anagram.
'lame' is an anagram of 'MEAL'.
(Other definitions for meal that I've seen before include "Food taken at a particular time" , "Breakfast, dinner or tea" , "Breakfast, dinner or supper" , "Breakfast, lunch or dinner" , "dinner, maybe" .)
