Need Cocktail/Drink-Appetiser suggestions

Yo! Scooter Rally next weekend, and it is a camping one up in Guernville on the river! We're also welcome to get there however we like, so being the cushy-assed camper that I am, I'm just gonna drive my truck up and bring all my camping acoutremont.

Because I'm bringing crap-a-plenty I figured it would be fun to put on a little cocktail hour, with a drink and a complementary appetiser. 
But I'm having trouble coming up with something! 
The drink I'd like for it to be relatively easy to make (altho I like the idea of mojitos, they can be hard to make, unless I perhaps do a whole pitcher sans ice)
For appetiser, it's gotta be something cold really. I'm camping, won't have stove, oven etc. 

I thought of where you do bread topped with mozzerella, tomato, basil and olive oil, but couldn't come up with a cocktail to go with it, I kept thinking Sangria cause it's kinda spanish/italian?

Then, there is the Sat night food, which will be a big luau (pork, chicken etc), so I could do something themed with that. Maybe some kind of fruit salsa, or prosciutto wrapped melon, but not sure what cocktail would go with that - mai tai, jungle juice?

whatcha got for me!
