Oatmeal is an awfully difficult dish to make photogenic.
It is however, reliably tasty and easy to make. The basic recipe is 1 cup liquid to 1/2 cup oatmeal. I use soymilk, and I throw in a peeled and diced apple, a few walnuts, 1/2 tsp cinnamon and some stevia. Toss is all in a pan over medium heat, stir every now and then, and cook until most of the liquid is absorbed.
