Canning beef stew. Takes approx. 2 hours start to finish: canning is actually a great time saver. Two hours today can mean having six or more meals ready to go at a moment's notice. It's the new tv dinner, but it is healthier and doesn't require your freezer!
Dehydrating is a bit easier to do than canning because you prep the veggies or fruits and can let it sit in the dehydrator unattended. Because it’s less of a time investment, I did it a lot more when I was working and going to school and time was at a premium. You are also able to do any sized batches, which is great for those of us with smaller gardens who don’t always have enough for canning.
