Powdered eggs and powdered milk.

Don't see why not? You pour milk on your Cheerios... this way saves a step in the process. It's what I do when I want milk on my granola on trail, but I usually just eat it out of the bag dry.

To each his own!

That’s pretty much what all the packaged backpacking granolas are; some powdered milk and granola. Perfectly delicious.
