We had this at this rad tapas bar called BarAcuda in Hanalei, Kauai. All the tapas there are so simple and delicious (besides the damn fine cocktails), and most are really easy to copy at home. This one, for example.
In a heavy cast iron skillet (because it works well and looks cool), saute a bunch of grapes, stem still on, in some olive oil. Put the grapes in a pre-heated oven @ 350* for maybe 30 minutes, until the grapes are really wilted. Cromble over some bleu cheese for the last 10 minutes. Serve with little toasts or crustini. The result are these sweet and juicy grapes, contrasted with the sharp bleu cheese and the crunchy bread. This is great to serve while you're waiting for your main course to finish.
