A friend of mine is attending a neighborhood block party this weekend and has asked me for some advice. She was asked to bring some type of appetizer. It's supposed to be really hot this weekend (like in the 90's), and although the party is in the late afternoon/early evening, she doesn't want to bring anything that will spoil by sitting out for a little while.
I'm at a loss. The only suggestions that I have come up with so far are some type of cheese straws or something like a caponata. Excluding mayo and sour cream based dips/spreads, I can't think of another suggestion.
Does anyone have any ideas? Thanks!
