Fairies: team tucking into pastry dishes? (6)
I believe the answer is:
pixies
'fairies' is the definition.
(pixy is a kind of fairy)
'team tucking into pastry dishes?' is the wordplay.
'team' becomes 'xi' (eleven, a football team).
'tucking into' is an insertion indicator.
'pastry dishes?' becomes 'pies' (I've seen this before).
'xi' going within 'pies' is 'PIXIES'.
(Other definitions for pixies that I've seen before include "Elves, imps" , "Little (mischievous) people" , "small fairies in children's tales" , "Mischievous fairies" , "Small supernatural beings in fairy tales" .)
