My American Harvester dryer is old, but still works. It has dried venison, apples, tomatoes, peppers, mangoes and even liver for my sled dogs when we lived in Arizona. I don't recommend drying liver since it stinks beyond description.
Here is a container of tomatoes. The flavor is sweet and intense. If you live in a hot and dry climate, you can dry them in a screened-in porch. We'll use these as snacks and on sandwiches.
