I want to substitute liquid oil with a dry product I would like to know if there is a dry food product available that is a good substitute for vegetable oil or butter.

I want to package dry mixes that I can take camping with me where hopefully all I would need is to add water to cook it.
Bisquick is a dry product that contains partially hydrogenated soybean and/or cottonseed oil and leavening. You can get recipe ideas from their website. With the Bisquick, some powdered eggs and powdered milk, you could create all kinds of fun mixes for camping.
