I have this argument with my wife often. I like to cook, and for me cooking is more than taking frozen meatballs and dumping them into a pan full of jar pasta sauce. I would rather make the sauce, maybe have some meatballs made in advance. My wife seems to think that pre-made stuff or mixes are the way to go. I would rather just make pancakes scratch, which isn’t hard, where she would rather I just open the mix, add water, and make the food. But I do agree that having a frozen lasagna is better than taking the full effort when I just want to get dinner going. So where are your eat the pre-made vs make it from scratch?
If you can, just do one pot of something that makes leftovers that hold well and are easy to reheat. After you get one thing, it gives you some breathing room for the next couple days.
I try to make a big pot of something on Sundays, so I don’t have to think about cooking Monday, maybe Tuesday. That gives me a little breathing room. I also make stuff I can portion and freeze - again, gives me a little breathing room.
Last week I was under the weather for 4 days, I just grabbed stuff out of the freezer and threw it in the toaster oven. Zero effort for my sick self. Now I need to restock what I used.
