Put desired amount of oatmeal in bowl and sprinkle with salt. Cover with warm water, about 1/2 inch above oatmeal. (This will depend on how thick you like your finished oatmeal. I like my oatmeal rather runny, so decrease the water if you want a thicker oatmeal.)

Microwave for one minute on high, remove bowl and stir. Microwave 30 seconds, stir again. Continue to microwave in 15 second intervals, stirring after each 15 seconds, until oatmeal reaches the desired consistency. I cooked mine about two minutes for regular oatmeal. Be careful that it doesn't boil over when you get to the end of the cooking time. Remove oatmeal and stir in 1 tablespoon peanut butter. Sprinkle with ground cinnamon if desired. Serve hot.

From kalynskitchen.blogspot.com: "Types of oatmeal: There are three types of oatmeal: instant oatmeal, quick oatmeal, and regular oatmeal (also called rolled oats). Since the less processed foods are, the lower the glycemic index, regular oatmeal is best for South Beach, and that's what I used when I made my oatmeal. You could use quick oatmeal if you prefer it, but please, don't use instant oatmeal. Even if you're not on South Beach, it's overprocessed for the sake of saving a couple of minutes of cooking time, and much less nutritious."
