A few years ago, I got tired of buying a box of granola for $4 every few days because we eat it a lot, and I kept thinking about the cost per ounce, and how absurd it was that we'd maybe be able to get 8 bowls worth on our yogurt which ends up being like 50 cents per 1/2 cup, give or take. I knew it would be cheaper to make my own, especially since I have that magical item in my purse that allows me to shop like royalty; I'm talking about the CostCo card!
After some loose inspiration from a recipe in Real Simple, I doubled the batch so it would last us at least 2 weeks, not to mention I constantly alter ingredients, embellish a bit and switch things around as I'm inclined to do.
