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?
Compromise, then?
Perhaps every other night you can cook from scratch, and cook as she likes on other days. Or, you could try to replicate the flavors she’s looking for in your cooking. Involve her, have her try tasting some sauce you’re making or whathaveyou and then try to see if you can nudge the flavors in a direction she likes.
