Basically, it means you get in mind what to cook for dinner before you start feeling hunger pains. Some veterans even plan days(!) beforehand. This runs contrary to every bachelor's mindset, especially mine, so I'd like some pointers from More bacon than the pan can handle's readers.
Probably the biggest obstacle is my own low standard. When thinking of food, the immediate utilitarian purpose is to erase the pangs. This can be met as easily with cardboard as with gourmet lasagna, but one has the advantage of being quicker. While I do enjoy taste, I regard it as a fleeting pleasure and not always a driving requirement.
Eating with others is a different story, altogether. I'll gladly make a meal worthy of silverware if someone else is enjoying it with me.
On a slightly related topic, have you ever seen that place called "DreamDinners"? I don't know why, but the name isn't appetizing to me. Dreams I associate with fantasy and clouds and fluff and unreachability. Dinner's got to be real, tangible, substantial, and filling.
