This year I have dehydrated apples, pears, bananas, peaches, strawberries, cantalope, pineapple, onion, red pepper, jalapeno pepper and mushrooms.  All have turned out fairly well.  I am not a big fan of dehydrated fruit, but the rest of my group has given all good reviews.  The problem is that while all are light, I now have a plastic grocery bag full of fruits/vegetables taking up space.  The fruit will be good snacks and the vegetables are great thrown into different meals.  However, none of what I dehydrated means I don't have to take something else.
