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?
As others say, premades are generally less healthy and carry more preservatives like sodium. I personally keep them on hand anyway in case I need something in a pinch, but even then I have a few easy meals if foods are stocked (like carbonara, which i make tonight!)
If you do go frozen for the wife, be sure to check what you’re getting. My step father has been having heart issues lately and I don’t think he realized his diet of mostly frozen dishes were putting him at like 300%+ daily intake of salt.
