In a separate bowl, disolve the salt in the water and then combine remaining ingredients. Pour wet mixture over Dry mixture. Mix well with a spatula, folding liquid up from bottom.
Spread out on a baking sheet and bake 15 minutes.
Turn mixture over and repeat until cereal is almost dry and nicely brown. (about an hour)
Turn off oven and leave door ajar.
Allow cereal to dry in warm oven for another 6-8 hours. If you have a large food dehydrator, you can experiment with this final drying step in there, instead of in the oven.
Optionally, if you like raisins and / or toasted coconut, now is the time to add them.
