During the pandemic I stopped eating out. I started making all of my own meals, and to make it easier to remember what to get at the store, I narrowed down to the same meals every day. It's been over four years now, and I'm fine with it.
No processed foods. Fresh or frozen vegetables and some fruit, organic chicken and milk, cheese, and nuts. That's about it. I spend 30 minutes per day total making meals. Once-a-week shopping is completed in 20 minutes, because I know exactly what I'm getting, and where everything is in the store.
I don't get bored with the meals, because boredom is all in the mind and I decided that food is not entertainment. That's all it took.
