Mix chopped tomato with sliced bread, though not to make a dish (9)
I believe the answer is:
dreamboat
'dish' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for dreamboat that I've seen before include "Dishy person" , "Heart-throb - met abroad (anag)" , "Mr Wonderful" , "Stunner (for drifting off in?)" , "Very attractive man" .)
