My wife and I hate having our entire weeks meals planned out. We love to be a little spontaneous so we have generally do less meal prep. We typically cook daily and gives us a change to make what we feel like each day.
We have a few standards that we always have ingredients for which we generally make. For these we just make them whenever we feel like it. We have a few staples that we can make using multiple different sets of vegetables like stir fry and pasta that we whip up with whatever we have around. For other recipes we just go to the store to get things just for that meal. We really try to avoid having too much in our fridge since it goes bad quickly with just two of us. Its more about general techniques or vague recipes.
