Foreign dish in spring served up with slaw, excluding the sides (6)
I believe the answer is:
paella
'foreign dish' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for paella that I've seen before include "Make stew" , "Dish (not English)" , "Spanish dish of rice, shellfish and chicken" , "Traditional Spanish dish" , "Span. rice dish" .)
