It seems like everyone wants a quick and easy breakfast. Breakfast cereal is expensive and maybe not prime body fueling material ;)
In our house I try to keep 3 half-gallon jars filled up on the counter...
One holds pancake mix(homemade mix with the other wet ingredients listed on a piece of masking tape on the jar), one holds instant oatmeal (homemade again...quick and easy!) and the third cocoa mix (ummm...that one looks empty! I'd better get on that!)
There are tons of recipes online for make your own mixes -- we have found that these are the most-utilized for us. Easy mixes which can be easily made by the kids or my husband for a quick filling breakfast for themselves (and their siblings, if it's pancakes!)
The oatmeal one is basically just regular oatmeal run through the blender to chop into smallish pieces, mixed with a little dry milk, cinnamon, brown sugar, and whatever I feel like throwing in (this mix has craisins and walnuts). To make, they just spoon some into a bowl and mix with as much boiling water that they need to make it the consistency that they wish!
