Should leftovers count as a real meal, not a last resort?

Leftovers are a real meal because, in many dishes, the extra day improves the food, and because planning for them is a legitimate way to cook well. Start with mechanisms. Braises, stews, curries, chili, and tomato sauces contain collagen, aromatics, and spices that keep dissolving and redistributing in liquid overnight. Starches in lasagna and baked pasta set, so slices hold together and cut cleanly instead of slumping. Marinated and pickled elements keep penetrating. Cooks often say these dishes taste better the next day, and the chemistry of diffusion and gelatin makes that plausible rather than mere sentiment. The strongest counterargument is that many foods do get worse: fries go limp, fish turns assertive, seared steak overcooks when reheated, and salad greens wilt. I concede all of that. But it argues for choosing dishes well, not for demoting leftovers as a category. Nobody calls a sandwich a last resort because soufflé collapses. There is also a practical case. Cooking a double batch once means the second meal gets the same care as the first, rather than a rushed weeknight improvisation. A planned leftover lunch is often better than whatever gets assembled at 12:30 with no plan. Last resort describes food you eat because nothing else is available. A meal you deliberately cooked twice as much of, so tomorrow is easy and good, is the opposite: it was chosen first.
