Best healthy meals to put in the freezer, not fridge, for long term prepping...?

I happen to be fine eating the same thing every day, even for all 3 meals.

I'm not working from home, and am looking to make meals that I can put in the freezer and pull out a bit ahead of time each time to thaw and then heat in a pan. The chicken/brocolli/rice type of meal, maybe a steak or fish dish too, so I can spend half a day cooking once a month in stead of one a week. Is this possible? For some reason there are a LOT of resources for people making meals for 5 days ahead and putting in the fridge, but barely anything for those who'd use a freezer. Is there a reason that I don't know about, or is it just because most people have time and the interest to cook on a weekly basis?

Thanks!
