OP here: I circled back to TJs and got the Eggplant Parm Sfogliatelle and the Fried Olive Bites; already have Mushroom-sherry Phyllo Triangles from Wegmans and my crackers and cheese assortment. It's a lot of cheese, but it'll do!

https://www.mediterraneanbakery.market on Pickett Street FTW!

They have a great assortment of freshly made apps (to be served hot and cold) that are delicious.

Costco or Trader Joe’s depending on how many people you’re feeding.

Vegetarian here, I picked up the fried olives appetizer from TJs and plan to have that. I also like the caramelized onion one. You could also branch out and have the asian style vegetable nests or veggie egg rolls. OR even some of the latin-style appetizers, they are all good.

I prefer the individual spanikopita pockets in the frozen section at Target to the big one that you have to slice from TJs. Grocery stores/WF would probably have something similar.
