I have a mix a little similar to Bannock, but more nutritious.
1 cup of Quaker oats that you have put in a food blender and chopped into a coarse flour.
2: A bit of dried milk (or normal milk if its cool out) that is just enough to wet the mix
3: A good squirt of liquid honey
Mix all together into a stiff sticky mix, put it into a pan with no oil and flatten it out to a thicknesss of up to .5 inch.
The trick here is to cook is slow so you would have to do it on embers or use a stove if you have one. It usually cooks in about 5 minutes and the result is a slightly sweet (withough being sickening after a couple) of rubbery Pizza looking stuff. Its dry to the touch, but moist in the mouth (although a brew always helps
)
I find it satiates the cravings for sweets in the afternoon when energy is flagging and since its a great mix of simple and complex carbs it will keep your energy level up for a fair few hours.
