Invest in canning equipment. Jars, lids, rings, canner(hot water bath does most things, need a pressure canner for meats and low acid veggies), tongs, and some canning books for recipes. Canned potatoes, beats, pickles, carrots, relish, salsa, peaches, apple sauce, apple pie filling(great for pies or just heat it up and eat it on ice cream), rhubarb, chutney, saskatoons and tomatoes so far. They’ll keep for 2 years, and with a garden each year you replenish as you go. The jars are an investment, new lids you need new ones all the time or else have to use the old glass lids and rubber rings. You’ll also need coarse salt, pickling vinegar, sugar and lots of potable water. You can also make and can beef stew and chilli with a pressure canner, lots of videos on YouTube for recipes and tutorials.
