1 cup Irish Oatmeal
4 cups water
Put it in a bain marie in the crockpot. Clean up is easy!
In the morning there's so many good things to put on oatmeal, such as: butter, brown sugar, cinnamon, chopped apple, walnut, greek yogurt. Sometimes I even put in cut up breakfast sausage.
I was using some aluminum foil between the bowl and the crock pot crockery. But it caused aluminum oxide on the inside of my crock, so now I'm trying a small dishrag between the two.
