You can also see this handy list of things you'd think you need a fridge for, but don't.
Indoor Garden: A nice addition is to also grow your own indoor garlic chives ( I have written about this), as well as your own herbs. That way, even if all you have in the house is pasta and some oil, you can add your fresh herbs and eat better than almost anyone!
Neighbors: Suss out some neighbours who you think would enjoy some of your leftovers. You will likely overestimate from time to time, and can either preserve your food in cool snow or water, or simply share with your closest neighbour. It's an instant way to build community, you won't just be creating dishes when you cook anymore.
