A few years ago, we spent a idyllic summer week in a small town about a half an hour south of Rome. Three of us were crowded in a small room with a hot plate in the corner. With no refrigerator, we assumed that meant we were going to eat out all week. Turns out, there's a lot of stuff that doesn't have to be refrigerated at all. We lived on salads, pasta, eggs, fruit, bread and cheese. No, there were no cold beers or icy drinks (Italians are not big fans of ice) and we strolled out to get ice cream at the local gelateria at night. But we had butter and Nutella on our morning bread, big salads and pastas for lunch and dinner and we snacked on cheese and olives and dried salamis. We didn't starve and we didn't get sick. We realized that we put a lot of stuff in our fridge because it's convenient or because we keep it for too long. But, apart from milk and raw meat, we discovered that many of the foods that make up our summer menu and that will be eaten within a few days can be left out.
Could you consider turning off your fridge for a weekend? A week?
