Instant Oatmeal Packets

We are going camping next month, and I have been dying to find an instant oatmeal recipe that works well. Marix loves oatmeal, but the organic instant oatmeal packets are so expensive, and don't come in any other flavor that is safe for him except for brown sugar. Blend 1/2 Cup of oats in blender until powdery. Into each of 10 ziplock sanwich bags combine: -1/4 C. regular oats -2T, powdered oats -1/8 to 1/4 t. salt -2t. brown sugar -1/8t.cinnamon I like to add dried apple chunks or dehydrated apple bits. I have also tried rasins, and dried blueberries. I want to try dried bananas next. When these bags are filled, store in a dry cool place. When they are ready to be used, empty packet into bowl and add 1/2 C. boiling water and let sit until thick, stiring slightly.
