Mix peeled and diced apple with lemon juice and cinnamon. Stir well to coat evenly apple. Cover and put in the microwave on high for 3 minutes. Add sliced ​​bananas. In a separate bowl, combine oats, milk, vanilla and a little cinnamon. Stir well and cook in microwave on high for about 3 minutes (until oats rise in the bowl). Mix fruit with oatmeal and add chopped walnuts. * The original recipe oatmeal and milk are a half, but I like it more. Also, milk is flavored with vanilla and vanilla is not added separately.
