Re: iftar party and dinner menu
OP, you should consider if you are serving the dinner before Taraweeh or after taraweeh.
if you are serving it before tarawaeeh prayers then you won’t have much time in between the iftar time and esha time. so i suggest that you keep only one dish for dinner as people can not have a full fledged dinner right after the iftari anyways.
so a dish like pulao or biryani or better yet Chinese dish like fried rice with chicken Manchurian/sweet n sour chicken/garlic chicken etc would go better. If you want to keep a curry based dish as well, then i recommend not to keep shermals or naans with it as one tend to get heavy with it. Keep chappatis.
for dessert, just keep icecream or kulfi.
for Iftar: If you can, then get the frozen packs of samosas and spring rolls and fry. but if you must make them at home then either do samosas or rolls.
Make chana chat, you can boil a day before and mix up with spices, onions,yogurt. that would be easy.
Fruit chaat for 25 guests would be labour intensive as some of here have suggested, so omit that.
make pakoras and kebabs
keep sherbat/drinks/milkshake/tea and dates and that should be a fine iftari.
