Vegetable dish with occasional chunks of ham, too (6)
I believe the answer is:
potato
'vegetable' is the definition.
(potatoes are sometimes considered vegetables)
'dish with occasional chunks of ham too' is the wordplay.
I cannot quite see how this works, but
'dish' could be 'pot' and 'pot' is found in the answer.
'of' could be 'o' and 'o' is located in the answer.
The remaining letters 'at' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for potato that I've seen before include "Vegetable - a hot one is trouble" , "Food item (with eyes?)" , "The vegetable is just too pat" , "It's often baked" , "Root vegetable" .)
