Hot stuff put in chef's yummy starters (5)
I believe the answer is:
spicy
'hot' is the definition.
(I know that hot can be written as spicy)
'stuff put in chef's yummy starters' is the wordplay.
'starters' indicates taking the first letters.
The initial letters of 'stuff put in chefs yummy' is 'SPICY'.
(Other definitions for spicy that I've seen before include "(Of food) hot" , "(Of flavours) hot" , "Hot-tasting" , "Mildly indecent" , "Pungently flavoured" .)
