Food fatigue is over rated.
I've been on a severely restricted diet for three years now due to reactions to food from a mast cell disorder. Essentially all I can eat is oatmeal and chicken, breakfast, lunch, dinner, snacks. I can small amounts of other foods on occasion to break the monotony but not enough to survive on if there's no oatmeal and chicken.
Yeah, it was tough at first, but you do get used to it. And hunger goes a long way to making the same thing day in and day out go down easier.
When you're hungry enough, you become grateful for what you have.
And you eat it.
If/when TSHTF, I have a couple months worth of chicken canned and frozen, and enough oatmeal to get by.
Then either God heals me or I die.
