Well, I started this thread, I might as well add some info on what I've been experitmenting with since.  I have been making simple biscuits out of Bisquick mix, water and powdered milk, and frying them sort of like a pancake, but thicker (and therefore slower over lower heat).  I'd add some powdered milk, garlic powder, onion powder or flakes, some basil, oregano and salt to plain Bisquick, for some tasty garlic biscuits.  On a shopping trip to find some powdered cheese (to make cheesy garlic biscuits), I saw that Bisquick is now making pre-made mix - just add water.  They also make a cheesy-garlic flavor.  No more need for powdered milk.  The cheesy-garlic ones are very good.  The plain is also good - adding the same ingredients above (minus milk) for the garlic-italian flavor.  One package takes about 2/3 cup water, and makes four nice big 5-6" biscuits - perfect for a group of four.  You could make smaller biscuits for a larger group.

I just empty the package into a big ziplock to pack/carry, add the water at camp, knead in the ziplock, and squeeze out of a cut corner to make drop biscuits.  Kneading by hand makes better biscuits, but makes more mess and requires an extra ziplock of plain Bisquick or flour for your hands and/or kneading surface.

Quick and easy bread for camp, no extra cooking utensils needed.
