Has anyone tried recreating and freezing any recipes for meal prep? I’m looking for ideas!

I'm expecting my third baby in March and am looking to stock up on freezer meals. I have a lot of recipe cards saved from the two years I used Hello Fresh back from 2019-2021. I tried using it more recently, like a couple years ago, but I was disappointed in the drop in quality. Anyway, was wondering if anyone's like me and has attempted to freezer prep certain recipes. Any favorites? Feel free to include any adjustments, too! One that I like for example is adding Italian sausage to the penne pomodoro bake for extra protein.

TIA!
