I have maybe half a dozen favorite meals. They have been probably 80%+ of my meals for 40+ years

I may or may not be ok but having a boring food routine does not particularly impair you

So the key is just to make sure what you eat provides a balanced diet? Because I’m a person who prefers to eat virtually the same things daily, with some “cheat” variance on weekends. Helps me hit my dietary goals needed to hit my fitness goals, and also makes for easier grocery store visits.
