Meat Loaf owns lease! (6)
I believe the answer is:
haslet
'meat loaf' is the definition.
(haslet is a kind of meat loaf)
'owns lease' is the wordplay.
'owns' becomes 'has' ('have' can be a synonym of 'own').
'lease' becomes 'let' ('let' can be a synonym of 'lease').
'has'+'let'='HASLET'
(Other definitions for haslet that I've seen before include "cooked meat loaf" , "Kind of meal loaf, eaten cold (6)" , "Chopped pork offal" , "Meatloaf" , "Meat product" .)
