I eat my morning cereal with Muscle Milk instead of milk. The stuff actually tastes good, unlike the ~10 other protein powders I've tried; and the nutritional information list looks like a multivitamin.
Pretty much daily now I drink a shake that contains 1 cup of dry oatmeal, some yogurt, a few cups of fruit, a banana and a tablespoon of peanut butter. Oh, and skim milk and occasionally some protein powder.
It's pretty good and it helps me keep my caloric intake at the right level.
