Cooking for one? Never heard of it

I'm still trying to figure out why I decided to make a huge baked ziti last night for dinner. I wasn't all that hungry but I made enough for six people anyway, and that left me with lots of leftovers. And because of the time it took to assemble and bake, I didn't eat until almost 10 PM. I guess I haven't gotten out of the habit of cooking for a group on Sundays even when the group isn't there. At least I'm all set for dinner tomorrow night before the opera and for lunch later in the week.
