I've got one of those too. Mines called the Pocket Rocket. Not sure of the brand name, but looks similar. I use it to boil water to make tea usually. I have a bigger stove for cooking, but for recipes where boiling water is necessary that little stove is awesome.

One of my favorite freeze dried items is hash browns. They come in little packages for four servings. Available at Wal-Mart. Just have to soak the hash browns for a few minutes in water then sautee them in a skillet with oil. You can add other veggies like tomatoes, green peppers, mushrooms and hot peppers too. The hash browns are seasoned with garlic and are delicious, as good as you can make with fresh potatoes.
