Do you know that you can microwave a single serving bowl of any kind of oatmeal? I do it nearly every morning:
3/4 c. oatmeal
3/4 c. water and about half that much more
microwave for 1 minute and 20 seconds (maybe a little longer experiment with your microwave)
Let sit for maybe 30 seconds to a minute.
Add what ever you put in your oatmeal and it is ready to eat.
