Meal planning to reduce food waste
Plan the week as one shopping list rather than as five separate dinners. Choose meals that deliberately overlap on fresh ingredients, so a bunch or a tub bought for one meal is finished by another.
Plan the cart, not the dinners
Most meal planning picks five meals people fancy and then writes down everything those five meals need. That produces a long list with a lot of single-use items on it, which is the shape of a week that ends with a full bin.
The alternative is to treat the week as one shopping trip that has to produce five dinners. The question stops being "what do I want to eat on Thursday" and becomes "what else can Thursday do with what Monday already made me buy".
Anchor on the expensive perishables
Start from the ingredients that are costly, perishable, and sold in awkward quantities — fresh herbs, cream, chillies, ginger, a large pack of chicken thighs. Build two meals around each rather than one.
Cheap, shelf-stable staples like rice, pasta and tinned tomatoes are not worth optimising around: they keep, and an unused bag costs almost nothing. Focus the effort where the waste actually is.
Aim to finish packages, not to use less
A useful mental test for each fresh item on your list: which meal finishes this? If the answer is "nothing does", either add a meal that will, or drop the recipe that needed it.
This is a different discipline from buying less. You are still buying everything you need for five dinners. You are just refusing to buy anything the week cannot finish.
Where this gets hard by hand
Doing this properly means holding five recipes, their overlapping ingredients, the package sizes your shop actually sells, and a budget, all at once. It is genuinely an hour of work a week, which is why almost nobody sustains it for long.
It is also a well-defined optimisation problem, which is what MealBudget does: you set a budget, choose the meals you like, and it builds the single consolidated list where ingredients are reused across the week.

Common questions
- How do I plan meals that use the same ingredients?
- Pick the expensive perishable items first — herbs, cream, fresh chillies — and build at least two meals around each, so the package gets finished. Do not bother optimising around shelf-stable staples.
- How many meals should share an ingredient?
- At least two for anything fresh and perishable. If only one meal in the week uses an ingredient that spoils in under a week, most of that package will be thrown away.
