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?
I have two suggestions: homemade pre-made, and why not both.
You can pre-make things like pancake mix, taco seasoning, pasta sauce seasoning, etc. write any instructions on the ziplock bag or container.
Instant items from a box or bag can usually be dressed up with fresh foods. If she’s cooking then offer to prep fresh items.
Also, respect that some people simple have no patience for cooking and don’t want to learn any. Communicate with each other to understand how to make it work.
