Most of the time the most expensive part of a meal is the meat.
Try adding a couple vegetarian meals to your repetoire to cut costs.
Beans provide a healthy protein alternative.
I got some grumbling at first, mostly from my husband, but my family as gotten used to, and get this, actually LIKE the vegetarian meals we tried. My husband has just requested we don't it more than once or twice a week:)
Even my pickiest, and I mean gag at food he doesn't like and takes and hour to eat ten bites picky eater, like the vege meals and occasionally will eat more than his required portion.
