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?
Most of the time I make my meals from the scratch. Exceptions are usually takeaway food; I only buy stuff like frozen lasagne and the likes very rarely, it’s expensive and it doesn’t taste as good. (In fact even a few of my spices is homemade.)
As others said, in your case (provided that you’re the one in charge of cooking) it might be sensible to buy the store-bought pancake mix for the sake of your wife, and then prepare the rest of the food as you typically do.
