Im going camping on a desolate island, what should i bring for food?

I have to take a small boat to this island, there is legit NOTHING there. We will have a camp fire and thats about it. The trip up is 8 hours giving virtually all food a chance to spoil. What are some good foods that you can suggest i take with me. So far i have sundried tomatoes, beef jerky and pudding packs in mind. I am also on my own to carry all my own gear so keep in mind im not in the best shape of my life. The trip in total is 3 days.
