I bought some pretty awful chocolate granola from Carrefour yesterday. It was on sale and there was 750g of it. I didn't relish eating it as it was, so I looked for a cookie recipe that used granola and found the recipe for Metropolitan Granola Cookies.
My egg wasn't large and even if it was, it would have been a large Spanish egg, and not a large American one. I guess this is why my cookies ended-up a little crunchier than they should have been but they were really good anyway!
If you ever buy a bag of granola you're not too happy with, I recommend this recipe for getting rid of it.
