I need to prepare a meal to bring to my family who is moving tonight. For 10ish people.

I usually bring people enchiladas, lasagna, chicken ceasar salad, or some kind of hearty soup (like chicken tortilla).

But it's hot, and I feel like those foods don't sound good on a balmy evening.

What would you make?

P.S. it has to be completely ready once delivered, because their kitchen is totally out of commission. So, nothing that needs to be warmed up or prepped at their house.
