8d Bear's fish found on open country (6)
20d Roger removed from annual dinner in style (3)?AY [presumably WAY(style) but can't piece together the rest of the clue]
11a Pellet Asian dish (6) ?ILULA
19a Jests about male with neat house (7)CHE??DS

Please note : With the final across clues, the letters I gave are for the grid entry, which is indicated by the wordplay, but is an anagram of the definition.
For the first two down clues, an adjective is required to make a two-word phrase, which is most likely a nationality (eg ENGLISH Mustard).
Many thanks in advance, and explanations please (I've been on this for two weeks!).
