Meat product in crate (6)
I believe the answer is:
banger
'meat product' is the definition.
(I know that banger is a type of sausage)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for banger that I've seen before include "Slangily, a noisy old car or a sausage" , "Old car (colloq.)" , "Sausage, firework and old car" , "Explosive" , "It might just drive" .)
