I'm looking for some ideas for a picnic on the grounds of a winery for about 8 people. It's a really special celebratory event and want to bring some elegant dishes that can be pre-prepared, travel decently well and are relatively easy to share. A variety would be ideal, anything from pate and charcuterie to hearty grain salads and dessert-y stuff. The winery hasn't been chosen yet, so I am not sure what kinds of wine exactly, but still looking for ideas.
Any recommendations would be deeply appreciated!
