Homemade fruit smoothies. It is a fast, healthy breakfast and my son is addicted to them. Milk, plain non-fat all natural yogurt (Dannon makes it), and fruit (fresh berries, melons, whatever). I can get him to eat fruit he normally wouldn't if I blend it in. If you pair it with a slice of whole wheat toast with a smear of peanut butter, you have a perfectly well rounded breakfast for toddlers with hardly any prep time.
