Bone Turkic people found in food (10)
I believe the answer is:
metatarsal
'bone' is the definition.
(I know that metatarsal is a type of bone)
'turkic people found in food' is the wordplay.
'turkic people' becomes 'tatars' (I've seen this in another clue).
'found in' means one lot of letters goes inside another.
'food' becomes 'meal' (meal is a kind of food).
'tatars' placed into 'meal' is 'METATARSAL'.
(Other definitions for metatarsal that I've seen before include "Bone in the foot" , "Part of foot" .)
