halwa, poori, and chanay of course!!! i've never been to a desi breakfast party that was without. but i don't know how well that will complement the "english" theme of this party. lol.
edit how awesome would it be if you could make tiny tiny pooris (like bitesize) with the chanas n sooji halwa already stuffed in them. so its not like a big messy breakfast but finger food style. just a thought :)
I would do...
an assortment of sandwiches (filled with both english and desi fillings)
mini samosas
keema puffs
mini quiches
savoury scones
cupcakes
jam tarts
french fancies
mini chocolate eclairs
custard tarts
