1. Bake bread.
2. Grow a garden, but only of things you really like to eat. It will either show you how easy it is to enjoy food you grew on your own, or give you appreciation for the effort that goes into the food at the store.
3. Make your own stock for soups, stews, pretty much everything.
4. Buy a really, really good knife. Just one. Keep it sharper than you think you need.
5. Forage! Mushrooms, strawberries, herbs (mint!), saskatoons. Even go to a U-pick farm.
