This is a tough one. How warm does it get on this hypothetical island? I’m a seasonal diner, so if the temperatures are really high I tend towards lighter fare. But perhaps I’m over-thinking this?
#1. Cassoulet! Beans, sausage, pork, duck confit, onions, garlic, tomato, etc. All wonderful things, with so many flavors.
#2. Wonderful bread. Crusty baguettes, fougasse, Pane Toscano.
#3. Cheeses. Brillat-Savarin, Grana Padano, Gorgonzola, Parmigiano-Reggiano, Morbier and Epoisse. A nice cheese board to round out the day.
I’m hoping there is good wine on this desert island?
