depends on your family’s preferences and the degree of formality of the gathering. if it’s a hair-down kind of thing and your invitees aren’t the kind that would hawww over non-desi food at a shadi related gathering, pizza is one of the safest things to go with when you’re feeding a crowd.
else if you go for desi, if you’re doing the roast, order either a mutton saalan and rice of some sort or maybe haleem and some kind of qorma. they’re good options for feeding numbers.
