A bit of chicken bone on a trip (5)
I believe the answer is:
thigh
'a bit of chicken' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'bone on a trip' is the wordplay.
'bone' becomes 't' (as in a T-bone steak).
'on a trip' becomes 'high' (I've seen this before).
't'+'high'='THIGH'
Can you help me to learn more?
(Other definitions for thigh that I've seen before include "part of body" , "Leg between knee and hip" , "Joint of meat" , "Ham" , "Upper joint of the leg" .)
