Cooked meat eaten in tube (7)
I believe the answer is:
sausage
'cooked meat' is the definition.
'sausage' can be an answer for 'meat' (sausage is a kind of meat). I'm not certain of the 'cooked' bit.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for sausage that I've seen before include "that should be edible" , "sort of roll?" , "Seasoned minced meat stuffed in casing" , "Eg, chipolata" , "Tube-shaped food item" .)
