Two recipes ask you to mix ground meat with panko, egg, and oregano — one Italian, one Greek — so those ingredients are already out and measured before you’ve finished the first night. Potatoes anchor the middle of the week in two completely different directions: crispy and lemony on a sheet pan Tuesday, rich and creamy in a gratin Thursday. A simple roast chicken closes things out on whatever night you need it, pulling onion, lemon, and butter that are already open. Twenty-seven items, four dinners.
