This is the way I currently make oatmeal most of the time. It's easier than trying to cook it in the morning!
2 cups regular or steel cut oats
6-8 cups water
1/3 cup brown sugar
1/2 tsp salt
2 tsp cinnamon
1 Tbsp butter
1 apple, peeled, cored, diced
1/2 cup raisins (optional)
Caution: The raisins will swell up and be very soft. I like them this way. You may not.
Modified from Mels Kitchen Cafe. (Removed maple syrup & blueberries, added butter, apples & raisins, changed sugar, increased cinnamon)
