I had Gronk Flakes for breakfast
They are like Frosted Flakes only bigger, thicker, Gronkier!
I believe they are only available in local (New England) Stop & Shop's, I got mine in Watertown.
I bought my brother a box for his birthday and he refuses to open the box, thinking they are going to be a collector item. (Yeah, maybe, but not in my brother's lifetime!) So I went out and bought my own box. A tasty breakfast with some sliced bananas and skim milk!
