Mix in protein powder with splenda or cane sugar, mix in maple syrup, fresh fruit, natty peanut butter, fruit preserves, or..
Take some canned fruit with light syrup and put it in a container, then add enough oatmeal (not too much) to soak up the juices. Let it set over night, and in the morning you should have a decent tasting version of oatmeal. Peaches work best.
And always add a good source of protein with it (along with it).
