For me burn out can take many forms, but not usually from the same meal over and over. I can do that for days.
I mostly get tired of deciding what to eat , plus the time spent shopping, prepping, and having to clean up afterwards. One pan meals are great.
For me, breakfast is the same, 6-7 days a week, and this takes away the stress of "what's for breakfast" and do we even have that?
Every time I'm at the store I know what to get for breakfast, and usually how much we need (and all the better if I buy a little extra ahead of time).
Every morning, it's the same routine... and it can be done quickly and without too may errors... (it. starts. with. the. coffee.)
For dinners, I like to do what my mom did, which is to cook large batches and freeze some for a later date. That way there's a meal waiting that would otherwise have taken all afternoon to prepare, just needing to be heated up.
It was said before, but I'll say it again... The shopping, preparation, and cleanup are bundled, and hardly any worse for a 4X batch than just ONE single batch!
Another of Mom's tricks was to cook a roast on a Saturday or Sunday, and have roast beef two nights, then grind the rest up and have hash two more nights (which was the real reason for cooking the roast in the first place...) Effectively turning the leftovers into a NEW meal.
We ate a LOT of leftovers growing up... cook one night, re-heat the next... rinse and repeat...
These days, I eat most of the leftovers since my partner doesn't think they are as tasty reheated (I often skip the reheating anyways).
So, they become lunches or snacks, or I'll eat it again for dinner and she'll have something else.
Last night, we had chicken stir-fry, and so we got enough chicken for 3 meals and cut it all up and froze 2 portions for later, ready to just thaw and toss into the wok. Leftovers tonight.
Tomorrow (and the day after), turkey, butternut, and kale scramble.
Of course, there's always a jar of sauce and a box of pasta in the pantry.
