Pour out the milk. It may not be sour, but your cereal doesn’t need it any more. No-bake peanut butter cereal bars are even better than a big bowl of O’s – and easier to eat! This healthy recipe offers lots of whole grains and very little calories per serving. All it takes is 30 minutes on Sunday night to mix, pour and set in the fridge. Breakfast to go, anyone?
