Apply versions of a recipe. The basic version is the cheapest with the most crucial ingredients and the next version includes nice to haves with a reasoning why it can be added (flavour, good combination, effect on the body,…) and the add ons are sorted by price so when a diet is created, it is automatically low budget but every time you get the option to upgrade and create the perfect version for the occasion.

In combination, the meal planner should be adjusted for meal prepping if desired. Instead of a big shopping list for the week, you can shop smarter by buying more of one kind for less diverse meals and you could see in the shopping list the differentiation between crucial and optional ingredients.
