Prepares tomatoes perhaps, and other items? (8)
I believe the answer is:
sundries
'items?' is the definition.
(I have seen 'Miscellaneous items' mean 'sundries' so perhaps 'items' could also mean 'sundries')
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for sundries that I've seen before include "Miscellaneous objects, incidentals" , "Miscellaneous unspecified things" , "Miscellaneous objects, stuff" , "Odds and ends" , "Extras" .)
