BBQ Dessert

So I am going to a fun little BBQ tomorrow for an end of summer get-together with friends from work.  All the normal fixin's will be there but I am going to bring a dessert. But what kind of dessert!??!  Obviously from what I am reading, something fruity and "cool" is best for this type of occasion.  So I headed over to some of my favorites sites and looked for ideas. 

Here's what I've found so far:

Strawberry Angel Food Dessert

Blueberry Buckle

Homemade Mint Chocolate Chip Ice Cream

Any suggestions??
