All the information on the internet I can find about frying a turkey outdoors involves a propane burner. Wouldn't a portable induction stove be safer, because there is no flame? I recognize that I would need a more expensive stainless steel pot than the more common aluminum ones. Are there any other limitations that I would run into? 
Egg whites is widely suggested as a way to do this.  I also see honey being recommended.  In either case, don't mix the granola as it cooks, perhaps turn the larger chunks gently, 1/2 way (or more) through the cooking time.
