Southern dish (5)
I believe the answer is:
grits
'southern dish' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for grits that I've seen before include "US dish of boiled maize kernels" , "US version of Porridge" , "Treats a road in winter weather" , "US dish of coarsely ground grain" , "See 1" .)
