I found this idea in the cookbook "Family Feasts for $75 a Week" by Mary Ostyn. I picked it up from the library and then ended up buying it. It not only has good recipes, but just lots and lots of great basic ideas for how to save money in the kitchen.
I tried this today, and had four kids eat it all up. Anything that everyone will eat gets 4 stars around here! Plus it took about 15 seconds to get ready, and then was done right as the last kid drug himself out of bed.
The basic idea:
Put 4 cups cold water and 2 cups quick-cooking oats into a rice cooker and turn on.
When it is done cooking (mine takes about 20 minutes) you could add whatever you wanted to.
Her recipe suggests:
Stir in 1/3 cup brown sugar, 2 Tbl butter and 1 tsp vanilla.
I added some cinnamon, too. The kids said it tasted like the Quaker "cinnamon roll" oatmeal.
