I looove oatmeal. I love adding fruit, right now that they're in season- cranberries!! Or blueberries, chopped apples, bananas, etc. Cinnamon is a must!! To get in some extra fiber, sometimes I add 1/4 c. of Fiber one cereal. And after it's cooked I add a couple scoops of cottage cheese for more protein. (sounds weird until you try it!) If you don't mind the artificial stuff, you could try some splenda or other sweetener also.
For the easy microwave packets, I love the Sturm's Flax & cranberry or blueberry oatmeal or the Quaker Weight control banana bread or cinnamon. HTH! I also make my whole wheat pancakes w/ oatmeal & banana bread too!
Also, try the steel cut oats, they have a totally different consistency than rolled oats but are really good too. It just takes longer to cook!
