So today I tried the whole oatmeal/rice cooker idea and it worked great! My only suggestion is that if you make a single serving, don't let it sit on "warm" for too long.
It was great, though...i threw the oatmeal and raisins and water in the rice cooker and then went upstairs to finish drying/curling my hair. When I came down, it was all cooked and ready to eat...so good! I definitely see me eating a lot more oatmeal in the future!
