I currently don't own a dehydrator and I'm going strong on FBC meals. I've tried out 3 of them and I don't need a dehydrator at all, although it would increase my options significantly.

You can buy instant rice at the grocery store, pouches of chicken, dried fruit like craisins, bullion powders/cubes, and all assortment of spices. From this and other grocery store fare I can put together (so far) 3 dinners, lunch (which isn't really FBC), and of course my traditional oatmeal breakfast. Eating oatmeal out of a freezer bag is so much easier, clean-up wise, than cooking oatmeal in a pot.

So, give a few recipes a try. Worst case is you will forgo some dried vegetables that you could otherwise throw in.
