I love all kinds of hot grain cereals, whether it be oatmeal, or grits, or cream of wheat/rice or multigrain cereals. I experiment with any number of fruits, nuts/nut butters, spices etc... whatever strikes my fancy. I love them all. Steel-cut oats are fabulous though, I agree.
In the case of grits, I have been known to try savory options using "butter", soy cheese, veggie sausage... I just love to experiment with my hot cereals, adding whatever I have on-hand.
