In the US, there aren't many options for whole, prepared foods (meaning someone prepared the food from whole ingredients, fresh) for various reasons. One that is common, for example, is a rotisserie chicken.
If you go to Asia -- Japan, Taiwan for example -- you'll find cheap, fresh, prepared whole foods everywhere to the extent that many households have very small refrigerators and many families have access to prepared whole foods even without having to expend the time cost of cooking at home.
For a dual-income household, this is a big win.
There's various reasons for this: lower labor costs, smaller land mass/higher density, better access to local/fresh ingredients, more favorable climate and longer growing seasons, etc.
Apples, Bananas, Carrots, Milk.
I imagine there are other foods too. But its weird to see people think they don't exist.
