Hurrah! Vodka melon time! Unfortunately, I don't reckon you'll have time to make this as it takes about a week, but it's good to know - take a melon, bore a hole in it, stick a funnel in the hole, pour vodka into the funnel every day, then at the end of the week cut it open - et voila! Highly alcoholic slices of melon!
Otherwise, there's always salsa dip - tinned chopped tomatoes, an onion, a red a green and a yellow pepper, some garlic, spices, and as many or few chillis as you wish - chop em up, stir em together, dip things in it. Easy peasy.
