The whole enchilada (3)
I believe the answer is:
all
'the whole enchilada' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for all that I've seen before include "that's as many as there are" , "Everyone - complete" , "Avenue, walk or garden path" , "Garden path (Fr.)" , "without exception" .)
