I went through the list of meals we made from $5 Dinners (from this package), and picked out the ones we liked the most: Chicken Cacciatore, Chicken Chili, Orange Pork Chops, Cheeseburger Soup (except Mr. Fixit likes it without the rice and cheese, served as pasta sauce), and Chinese-style Beef and Broccoli. Those we'll make again this time. I'm also planning on adding Cranberry Pork Chops, Honey Garlic Chicken, and Crock Beef Sandwiches from Saving Dinner.
This approach seems to have worked well enough for our current meal needs that we're willing to give it another go. It works especially well when we divide the meals-for-four into meals-for-two, because we can always cook two bags at once if we need them, and if I know it's going to be just two of us eating, I use one bag and the smaller slow cooker. Sometimes I remember to thaw meals overnight in the fridge, and other times I dunk the bags in water for twenty minutes--both ways seem to work. Our little slow cooker cooks hotter than the 3 1/2-quart one, so I set it on low and keep an eye on it; if the food finishes earlier than expected, I take it out and reheat it later. (I would just use the big one, but for smaller amounts, the 2-quart pot is handy.)
We are planning on going out sometime this week and picking up groceries for Marathon #2.
