Dish on a university table (7)
I believe the answer is:
plateau
'table' is the definition.
(I've seen this before)
'dish on a university' is the wordplay.
'dish' becomes 'plate' (plate is a kind of dish).
'on' means one lot of letters go next to another.
'university' becomes 'u'.
'plate'+'a'+'u'='PLATEAU'
(Other definitions for plateau that I've seen before include "High flattish area" , "High flat land" , "Stop progressing" , "High plain" , "Flat area of land" .)
