Coast of Toulouse, as I described (7)
I believe the answer is:
seaside
'coast' is the definition.
(I've seen this before)
'of toulouse as i described' is the wordplay.
'of' says the answer is hidden in the clue.
'SEASIDE' can be found hidden inside 'toulouse as i described'.
(Other definitions for seaside that I've seen before include "A place on the coast" , "Coastal area" , "Disease (anag) -- coast" , "holiday venue" , "Shoreline" .)
