The trickiest part about keeping up the black and white theme is deciding on food. Here are a few unconventional ideas:
Grill a white fish like Halibut, making sure that each side has a few black char marks from the barbeque.
Create a white bean soup, or provide a stark contrast by mixing dark kale leaves with white beans for a side dish.
Rice is always an easy "white" side to serve!
Caribbean black beans are another delicious side for your halibut.
For the bread, try using rye and ciabatta rolls for contrasting colors.
Dessert is the fun, easy part. Either do it buffet style with classic black and white favorites like S'mores, Chocolate Chip Cookies, Oreo's, Hostess Cupcakes and milk, or create a signature dessert just for the occasion.
If you're creating a large cake, consider decorating the outside like a domino - it's easy and keeps dessert perfectly on-theme! For simpler desserts, bake chocolate and white cake cupcakes and frost them with the opposite color frosting, or create an amazing Death by Chocolate Layered Mouse in a clear bowl that shows off the contrasting layers.
