Dang. That's pretty hardcore Harry. I'm afraid I have no ideas on what to blend with your hard boiled eggs.
Have you thought of scrambling 3 or 4 of them and substituting a protein shake for the rest every once in a while?
Or maybe boil a few, scramble a few, and add a shake.
Or a few over easy, a couple boiled....
Or maybe replace a few of the eggs with a chicken breast (or Canadian bacon) every once in a while.
Hope this was at least a little helpful..
