Energy, I needs it.

I need to find some sources of protein for breakfast… other than eggs, soy, or dairy. My thyroid seems to be struggling lately, or so it seems, because my energy levels are bottoming out by 10 am. I can’t eat the aforementioned on a regular basis because of my thyroid meds, so I’m in a terrible bind. It seems like soy and dairy are hiding in every protein replacement product I find 😦 . What to do? It seems like nut butters are one of my few options, but I tend to eat those for lunch and would hate to eat the same thing twice in so many hours. Ack.

Dear strangers, any suggestions?
