To some extent corpulent, I love a bit of food (6)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
lentil
'a bit of food' is the definition.
(I've seen this before)
'to some extent corpulent i love' is the wordplay.
'to some extent' indicates the answer is hidden within the clue.
'LENTIL' is hidden in the letters of 'corpulent i love'.
(Other definitions for lentil that I've seen before include "Lintel (anag.)" , "Pulse used in cooking" , "Small seed used for food" , "A legume, its seed" , "bit of food" .)
