My first dinner party

Would I need a BBQ/grill for it? i know it sounds like a DAH!Q but i can only use stove.cant use the oven, no toaster-oven. =// but still...send it on over..

So frozen kababs are only okay for a week?
The kind of raita i have in mind (that my mom makes for us) has boondi/choti pakoriyan in it with onions and tomatoes... come to think of it, my bhabhi makes it really well...

I want to swap the mash ki daal for alloo gobi. Is it okay to chop gobi and peel/chop potatoes and leave em in the fridge? If so, for how long? I'm assuming potatoes and gobi won't fare as well as chopped onions and tomatoes? I will make that one day in advance, as well as the chicken makhni.

It looks like the only fresh things will be the biryani and salad/raita.........
