I can't cook worth a darn, and I'm a cheap S.O.B., so I prefer Marie Callendar's frozen dinners. Especially when I can get them on sale, for like $2.00 to $3.00 each (though I keep forgetting to bring the coupons that will take another $0.50 off...).
The ones I like the best are: Herb Chicken, Honey Roasted Chicken, Slow Roasted Beef, Turkey Dinner, and the Mushroom Beef (or whatever it's called).
