Food for team changing before dance (8)
I believe the answer is:
meatball
'food' is the definition.
(meatball is a kind of food)
'team changing before dance' is the wordplay.
'changing' indicates anagramming the letters.
'before' says to put letters next to each other.
'dance' becomes 'ball' (ball is a kind of dance).
'team' is an anagram of 'meat'.
'meat'+'ball'='MEATBALL'
'for' is the link.
(Other definitions for meatball that I've seen before include "portion of food" , "Small globular piece of mince" , "Something to savour" , "Globular food item" , "Food made from minced beef" .)
