Meal without starter situated inside (5)
I believe the answer is:
inner
'situated inside' is the definition.
(I've seen this before)
'meal without starter' is the wordplay.
'meal' becomes 'dinner' (dinner is a kind of meal).
'without starter' means to remove the first letter.
'dinner' with its first letter taken off is 'INNER'.
(Other definitions for inner that I've seen before include "Part of an archery target" , "(Hit on) part of target immediately next to the bullseye" , "closer than magpie" , "Ring round the target bull." , "Nearer to the centre, deeper" .)
