Meal Planning

Weekly planning, batch cooking, and pantry strategy that sticks.

Most meal-planning advice is about willpower and containers. The posts here are about money, and they lean on one finding from our own priced baskets: over half of what you spend on a dinner is package remainder, food you bought because stores sell packages and recipes call for amounts.

That reframes the whole exercise. Planning saves money mainly by spending last week's remainder instead of re-buying it, which is why a second week built on the first can cost less than half as much. These posts cover how to sequence meals around what a package actually leaves behind, which leftovers are worth planning around and which are not, and what the research does and does not show about planning and grocery spend.
