Gazpacho Pairing?

[LunaChick]

Hi,
I'm new to this board, and my wine knowledge is minimal. I'm hoping someone will answer my question about what to drink with gazpacho - we'll be serving garlic crostini, shrimp (grilled w/ a little oil/garlic), and possibly scallops.
I was thinking a sparkling wine (budget won't allow champagne!), or maybe a Chardonnay or Pinot Gris? We were thinking of something Spanish, but it doesn't *have* to be...
Any suggestions will be greatly appreciated!
TIA!
