This is pretty much how I've always done it with a little modification. I have to eat a little more often so generally didn't heat up anything for lunch then do a mid-afternoon meal that I split up and used the other part for my supper.

By doing it later it's always stayed hot even in wide mouth containers and I can have a hot meal without much extra effort. Which also gives me some more flexibility on when I eat in the evening

I also like not having to rush and more time to explore/gather after I've set up camp.
