Grab and go or short notice catering ideas

I am attending a small gathering this afternoon, like 10ish people, and I'm expected to bring something tasty to contribute. I ain't turning on my stove or oven today in order to respect my struggling air conditioner. I'm also not feeling particularly inspired so I'm hoping someone will give me a great idea of something I can either order on short notice or a place with great grab-and-go options. I know I could just drop into a grocery store, but I'm hoping for something a tad more elevated than that. This crew likes really good food. Don't really care about cost as long as it's not insane. It could be one single half pan of food or maybe a small platter or something like that. I used to grab stuff from Gris Gris like red beans or gumbo but it ain't dere no more.
