We eat out once maybe twice a week or cook from scratch.
Edited...after reflection ... when I make lasagna I use barilla pasta, whatever jarred sauce is around, costco meatballs and premio sausage and mozzarella that somebody else made. I call this scratch, while recognizing one might actually make all the components really from scratch just as one might breed and raise the cow that makes the milk for the cheese.
But it isn't a tray of Stouffer's lasagna that I pop in the oven and heat up either.
