Planning food isn't really my thing.
I generally buy ingredients and then invent ways to combine them. Recipes are for cakes, bread and pastries not for a pasta dish, risotto or jacket spud. My home cooking really isn't very inspired.
But I found this, which I quite like. Tesco Meal Planner.
I haven't used it, but I think I might. I know Tesco has been in the news today because they don't seem to be very good at counting (massive profit overstatement) but they can get some things right.
