Heya, my family doesn't follow the PB to a tee, my child would get a treat or two a day (commercial or home-made, sometimes with wheat, and always with sugar, lol), and will have organic rice cereal for breakfast. My husband would eat something else sometimes. Otherwise, they just eat what I cook, and pack for their lunches, and because the food is tasty they don't mind that we do not have bread or pasta in the house. The biggest challenge for me is to make time to cook my husband's breakfast, otherwise he'd eat oatmeal. My 6 yo's favorite food is meatzza. Overall, mostly it is about replacing your side dish, particularly if you are not against eating tubers, so really no big deal.
