Yep, have "dinner foods" for breakfast. I had a nice bowl of my home made chili this morning. Beef, black beans, and veggies all in one bowl, and since I cooked a big pot of it on the weekend, I have enough for the whole week.
If you like cottage cheese, that's an option.
For the first 6 months on SCD (I'm 9 months in now), I wasn't eating beef, pork or chicken, so my main protein sources were eggs and fish. I very often cooked some tilapia in butter on top of the stove for my breakfasts. It is so thin that I could even cook it from frozen. I added green veggies and beans or lentils to the plate that had been cooked ahead in large quantity and just microwaved those while the fish cooked.
A small steak, some pork sausage you've made yourself ahead of time, some leftover rotisserie chicken...these are all great protein sources for breakfast. I always tell people, "When you think breakfast, think 'not grain' and 'not sweet'."
