No worries about growing zone, weather, space requirements just your dream garden.
I would love to be able to grow vanilla, they look really cool the flowers smell amazing and having a source of fresh vanilla beans would probably unlock some next level cooking. An olive tree would be cool too, I can eat unlimited olives and making my own oil would be awesome.
Any home-grown fruit is better than store-bought, but i've been liking store mangoes. All the people I know who've had fresh mangoes from a tropical place say they're way better fresh, so i'd be curious.
Tomatillos because all i have access to are canned ones
warm mango > cold mango
