In winter, just as in summer, it makes sense to buy food items that are available for sale in large quantities at low prices. At the end of summer, you can easily stock up for winter, without too much hassle.
You can roast peppers on the barbecue or in the oven, peel them and put them into small bags in the freezer. You can also make ice creams or sorbets with strawberries or other berries. Or how about freezing blueberries on a tray and then, putting them all together into a freezer bag? Making soups and apple sauces are also other ways of storing seasonal foods.
And all this at a fraction of the winter prices. You can see this using peppers as an example: they cost $11/kg in winter and $1/kg in summer.
