In the US (Florida), where at least produce is affordable. Otherwise, we plan meals around whatever is on sale. We don't eat beef, lamb or pork, but fish and chicken are going up fast, too! If sales are extra cheap (asparagus, blueberries, broccoli this month) I use a vacuum sealer and can freeze them a long while. Have to blanche vegetables first, berries just clean, freeze and seal up. If I find dry goods (rice, lentils, flour) inexpensively, I buy them now, while they are still affordable, and vacuum pack them into(reusable) canning jars. I seal and freeze what DH and I will use for a meal, so no waste. Here, I am what is generally referred to as a "prepper", and put something aside every week, for future needs. Our prices are going up just as yours are-shockingly. I worry about retired friends, on very limited income, while grocery costs seem to double every week. We are definitely sinking into a serious economic downturn here, and we have been prepping for months. We have curtailed unnecessary spending, because I don't want to look back and say "I shouldn't have spent that money on shoes/purses/junk, because now I wish I had more food in the house".
