For this round, I kept it very, VERY simple. Meat, marinades/sauce, freezer bags - that's virtually it. In a little over and hour, I was able to prepare 18 meals! Keep in mind I'm just talking about the "main course" here - when I prepare these, I'll still throw together some noodles, veggies, etc, but at least the bulk of the work is done.
The most economical way to do this is to buy meat that is near the "sell by" date - I was able to get chicken breasts for $1.29/pound, and still had 2 days before the "sell by" date ran (if you follow those kinds of guidelines of course, lol). I also got a good deal on the steak. Otherwise, at least go to a store where the meat is already on sale that week, and stock up. Make your freezer meals based on whatever is the most economical that week and it will save you a ton.
I cut up almost 20 pounds of chicken, putting them into gallon-size ziplock bags. I used our favorite marinades (general Tso's sauce, teriyaki, sweet and sour) along with a couple new ones that were on sale (I buy marinades when they're only .99 cents and I stock up!) For a few of the bags, I threw in pineapple for Hawaiian chicken, and you can also throw in frozen stir-fry veggies as well. I also bought some ground beef in bulk on sale - some was cooked/divided for burritos, some went into pasta sauce, and some was converted into delectable hamburgers. Here are the bags:
