I'm having my lab group (2 people) over to study this evening. I promised snacks.
Since I've been writing papers, studying, etc. etc. I haven't been grocery shopping in forever, and my good-hostess / foodie brain had atrophied.
Given a budget of ~$20, what would you serve? Assume access to a general convenience store / small grocery, not Dean & Deluca.
Thanks in advance, eaters!
