There are whole cookbooks devoted to make-and-freeze meals, where you cook like a month's worth at a time. That might help.
Otherwise, lasagne is an old stand-by.
When a friend had her baby, I went to the store and bought ground beef and chicken breast. From the beef, I made a chili, 2 baggies of spag sauce, and some kind of taco-bean thing.
With the chicken, I made a couple of curries, a couple of stir-fry type preparations, and a cream sauce thing. I bought various rices and noodles, and labeled each frozen item with its corresponding starch.
It was really only enough meals for one meal a day for maybe 2 weeks, but it was appreciated. There is a little extra prep involved with cooking the rice/noodles, but it is still a lot simpler than making the whole meal.
