Laurel eats unaccompanied tripe (7)
I believe the answer is:
baloney
'tripe' is the definition.
(thesaurus)
'laurel eats unaccompanied' is the wordplay.
'laurel' becomes 'bay laurel' (bay laurel is a kind of laurel).
'eats' indicates putting letters inside.
'unaccompanied' becomes 'lone' (on one's own).
'bay' placed around 'lone' is 'BALONEY'.
(Other definitions for baloney that I've seen before include "rhubarb" , "Tripe < , smoked sausage" , "deceptive talk" , "Cobblers" , "Nonsense; lean yob (anag)" .)
