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 make as much as possible to avoid the flavor additives, texture modifiers, and preservatives found in much packaged food.
I make waffles from scratch and freeze them for quick breakfast. Prep large pots of soup, chili, stew, etc and freeze in deli tubs.
But as to who is right? No answer on that. I have built up plenty of cooking experience so things that seem tricky or time consuming to other people don’t faze me.
