Thay sandwich is good, i've done it.
Now though, my breakfast is
5 egg/ground beef and cheddar/mozzo omelete...
6 wholegrain large pancakes/dash of honey
16ounces of milk
.....then, as soon as I'm settled in at work, I pop a PB sandwich and 16 ounces of milk (1hr later)
That's my total breakfast...
