Oatmeal. I've had oatmeal for breakfast most mornings for many years. Most often just plain old fashioned oats, and primarily with soy milk albeit at times with cow milk. All of the above dried fruits are great, dates, figs raisins etc. Walnuts, brown sugar, bit of maple syrup, protein shake, preserves, yogurt etc.
For many years i didn't even bother cooking it (yes the old fashioned oats) but lately am back to cooking. Steel cut are great too but for the prep time. Oatmeal.
