With the sweetness of the bananas you don't need much brown sugar. I really LOVE the crunch that the pecans add.
I'm going to tell you how I made it every morning. I have a ceramic cook-top stove, so if you have something different...you will need to adjust the directions.
Oatmeal with banana and pecans
1 cup water
1/2 cup quick cooking oats
~1/4 cup chopped pecans
Directions: In a small pot bring one cup of water to boil over high heat. When the water begins to boil, stir in 1/2 cup oats and turn burner off. I move my pot off of the burner for 30 seconds to a minute to let the burner cool just a bit. Then I put the pan back on the burner to continue cooking(with the burner turned off) while I do other things...like pack a lunch. When the oatmeal is the desired consistency, pour oatmeal into a bowl, top with sliced banana, pecans, brown sugar to taste and desired amount of milk.
