Hot stuff filled tortilla graduates consumed (7)
I believe the answer is:
tabasco
'hot stuff' is the definition.
(I've seen this in another clue)
'filled tortilla graduates consumed' is the wordplay.
'filled tortilla' becomes 'taco' (I've seen this before).
'graduates' becomes 'BAs' (people with Bachelor of Arts degrees).
'consumed' means one lot of letters goes inside another.
'taco' enclosing 'bas' is 'TABASCO'.
(Other definitions for tabasco that I've seen before include "Hot pepper sauce" , "Hot peppery sauce" , "Red pepper sauce" , "Hot red sauce" , "Spicy pepper sauce" .)
