What organic foods can you find in the supermarket?

It depends on the supermarket. Almost all have some foods that are organic, but some stores have a better selection. Most will have at least a small section of organic produce and organic products here and there in the stores. Others will have a "natural foods" section which may contain organic products, in addition to a section of organic produce. You really need to visit individual supermarkets to find out what organic foods they have.
