Smooth sorceress with no time for quick snack? (8)
I believe the answer is:
sandwich
'quick snack?' is the definition.
(I've seen this before)
'smooth sorceress with no time' is the wordplay.
'smooth' becomes 'sand' (sanding is a kind of smoothing**).
'sorceress' becomes 'witch' (I've seen this before).
'with no' indicates named letters should be taken away.
'time' becomes 't'.
'witch' with 't' taken away is 'wich'.
'sand'+'wich'='SANDWICH'
'for' acts as a link.
(Other definitions for sandwich that I've seen before include "Bread-based snack" , "The snack might result in bad chin wads" , "Pieces of bread with filling" , "Squeeze (between)" , "seaside town" .)
