1 hard boiled egg
Forgot them today. I remembered my peanut butter and jelly snack (spooned into a KFC cole slaw container - they are the perfect size, dishwasher safe and have a convex lid so your stuff isn't leaking out the sides when you close it).
So I made some oatmeal (I keep a stash in the cabinet in case I forget my breakfast)
Forgot it was bagel day. Which meant I did not need to have my banana & egg. Or oatmeal.
