I tried this one day when I had a bit of apple juice on hand. The only fat is from the oatmeal proper. If memory serves, there's 1 gm of fat per ounce of dry oatmeal. Feel free to substitute.
Core the apples, [peel if you insist] and chop. Chop the dried apricot. Combine the apples, apricot, raisins with the apple juice and heat to boiling. Let simmer a minute, then add the oatmeal. Cook for 5 minutes, then turn off the heat and cover for a couple of minutes. Serve over or with sliced banana.
