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?
Talk to each other, apologize, and compromise. Sometimes do it your way; sometimes do it her way. Understand and forgive each other, enjoy both approaches, and be happy about the situation.
