Bear Creek Country Kitchens--well, anything, really. Specifically, though, we like their Cheddar Broccoli soup and their Chicken Vegetable pasta.
For the soup (they also make a pasta w/ the same flavor that is just as good that I prepare the same way), I chop up and brown a couple chicken breasts and a full pound of frozen broccoli (or fresh, if I think to grab it), and then cook as directed on the package, making sure to scrape up all the brown bits from the bottom of the pan when I add the water.
For the pasta, I chop up and brown a couple chicken breasts, add about half a pound of whatever mixed veggies I happen to have in the freezer and cook as directed on the package. Sometimes I'll go as far as to mix up an egg and half a cup of plain yogurt or mayo and mix it into the sauce, and then pour the whole thing into a baking dish, top with cracker crumbs and bake like a casserole. Always awesome! :)
So there are two of my favorite "packaged dinners." Not much to them, but they are super simple and no one ever complains when I make them. :)
