Meat loaf half eaten during flight (8)
I believe the answer is:
escalope
'meat' is the definition.
(I know that escalope is a type of meat)
'loaf half eaten during flight' is the wordplay.
'half' means to take half the letters.
'eaten during' indicates putting letters inside.
'flight' becomes 'escape' (flight can mean an escape).
'loaf' halved is 'lo'.
'lo' placed into 'escape' is 'ESCALOPE'.
(Other definitions for escalope that I've seen before include "Thin slice of boneless veal" , "what might feature in the catering" , "food" , "Cut of meat" , "Thin slice of boneless meat" .)
