As someone with a limited diet, I'm always interested in finding new foods I can eat, or finding new parts of foods or plants that I can eat.
This is a link to a series of leaflets on South Pacific foods and it's simply wonderful. Lots of recipes, but also lots of practical advice on how to prepare these foods from scratch, or use them in recipes. There is information on more common foods like pineapple, or foods that folks in the west may not be as familiar with, like rarer nuts or tubers. Also some great information on food we don't eat here at all typically, but could - things like how to make and prepare fresh fig leaves, or the leaves from a chile plant or pumpkin, that sort of thing.
I totally recommend you check it out!
