Part of meal presented using salver, say (6)
I believe the answer is:
entree
'part of meal' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for entree that I've seen before include "Access - course at meal" , "Dish allowing one to go in?" , "Dish conferring right of access" , "Dish served between fish and meat course" , "Principal dish of a meal" .)
