I'm probably preaching to the choir here, but for convenience and price I dehydrate a lot of store bought frozen veg. It can sometimes be hard to get a good crop of sweetcorn and home grown peas are just too good to dehydrate so I buy bags of frozen from the store. I also like the bags of mixed peas, beans, sweetcorn and chopped carrot. You simply spread them out on the drying trays, leave to defrost and then dehydrate according to your dehydrator instructions. The beauty with this is you can do it anytime, it's fairly cheap, everything is prepared and if you don't have enough of something else to fill your dehydrator you can always fill it with more than one thing. Finally for those who don't have a garden, it's a great way to build up stocks of food that don't rely on electricity, or for long term storage and you still have some control over quality. Youtube has plenty of how to videos for the unsure.
