Quickly eat sandwich with zero content? (4)
I believe the answer is:
bolt
'quickly eat' is the definition.
'bolt' can be an answer for 'eat' (bolting is a kind of eating). I'm not certain of the 'quickly' bit.
'sandwich with zero content?' is the wordplay.
'sandwich' becomes 'BLT' (BLT is an example).
'with zero' becomes 'o' (O resembles 0. I am not sure about the 'with' bit.).
'content?' is an insertion indicator (some letters act as content for another word).
'blt' placed around 'o' is 'BOLT'.
Can you help me to learn more?
(Other definitions for bolt that I've seen before include "for security reasons" , "Runner" , "Find a bar" , "From the blue, it's a great surprise" , "playwright" .)
