Your preferred "O"?
We're pretty sure that most of our households have consumed some variety of the "O", Cheerios, Trader Joe's Oh's, Kashi's Heart to Heart, and there are so many others. While traditionally a breakfast item, these cereal items are toted in our bags and the kids bags as snacks, meals, and everything in between.
What O's do you stock in your household? What do you look for in an O? Price? Does nutritional content vary widely from product to product?
