This is one of my favorite mix-ins for oatmeal.
1/2 diced apple (about 3/4 cup)
2 tbsp raisins
1 1/2 tbsp brown sugar
1/2 tsp cinnamon
I made the oatmeal according to package instructions. Then I stirred in the brown sugar and cinnamon until blended. I stirred in the apples and raisins and garnished with an apple slice and more raisins. It was very yummy and filling!
