If you don't have good sun this time of year or just live someplace like the UK or PNW where they don't know what sunlight is, then you can use the conventional oven in your kitchen, @ 150°F or above you can dehydrate pretty much anything, it'll just take a day or two, you just want to keep the temp under 160° F and it'll go a bit quicker, just don't go above that or the food will cook more than dehydrate. Even a small toaster oven will do the job if you don't have a big batch.

It requires taking advantage of fruits and veggies when they're in season if you grow your own like I do, and you can keep a close eye on the grocery circulars to get stuff when it's cheap to dehydrate for camping food.
