Food : I'd drink the coconut water to stay hydrated and eat/make juice with pineapples, mangoes, oranges, dragon fruit, and avocados. I'd have a garden and plant potatoes, carrots, and beans etc. With fishing supplies and nets I'll get clams, fish, squid, scallops and shrimp. I'd literally eat tacos every lunch and dinner for the rest of my life.
Shelter : I'd live in a house by the beach, have a maid so I don't need to clean. My house would have patio so i could invite friends and family for barbecues and also to have a sweet view of the ocean. I'd also have bar to have my pina coladas. I'd have tons of windows for natural sunlight. There is no such thing as bugs so I don't need to worry about screen doors.
