United pea and tofu in blending soup (3-2-3)

I believe the answer is:

pot-au-feu

'soup' is the definition.
(I've seen this before)

'united pea and tofu in blending' is the wordplay.
'united' becomes 'U' (abbreviation).
'and' means one lot of letters go next to another.
'in blending' indicates an anagram (letters get blended together).
'u'+'pea'+'tofu'='upeatofu'
'upeatofu' is an anagram of 'POT-AU-FEU'.

I've seen this clue in The Times.
