Hey Primal Papa!
Your kids sound awesome - and is it wrong, I can't help but wonder what that neighbor girl DOES eat!?
For me, the quality of the food is a priority - I'd rather have 3lbs of grass-fed beef than a CAFO half cow. I find that it's not much more expensive (especially since you eat LESS when you're properly satisfied by food with good nutrients), and the way I feel justifies the cost.
Btw, for breakfast, I'll eat just about anything (if I'm hungry - if I'm not hungry, I don't eat, and I'm not hungry most weekdays when I wake up).
This morning, I had a beef shank and cabbage stew going in the slow cooker while I slept, so I chowed down a nice hot bowl of tomatoey cabbagey beefy brothy goodness.
I almost ALWAYS eat breakfast on the weekends, and it's usually some sort of bacon + eggs (sometimes an omelet) + veggies (garam masala roasted brussels sprouts are my current favorite) + sometimes a chunk of sweet potato w/grass fed butter, and coffee or tea.
Oh, and the bulletproof coffee doesn't taste that different than coffee with cream, FYI
keep at it - the first bit's the hardest!
ETA: Also, I notice peppers in almost everything you've posted (or maybe they're just sticking out and they're not really in everything...) - a lot of people are sensitive to pepper specifically (I know I don't digest red bell pepper skins very well), and perhaps even the whole nightshade family... something to think about if you're having to run to the bathroom all the time.
