Vegetable and bread regularly found on plate (6)
I believe the answer is:
radish
'vegetable' is the definition.
(radish is a type of vegetable)
'bread regularly found on plate' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'found on' means one lot of letters go next to another.
'plate' becomes 'dish' (type of plate).
The alternate letters of 'bread' are 'ra'.
'ra'+'dish'='RADISH'
'and' is the link.
(Other definitions for radish that I've seen before include "Hard vegetable" , "Sir had this vegetable" , "Edible small root" , "Pungent fleshy edible root eaten in salads" , "Hottish salad plant" .)
