These are things that I always do.
Prepare a meatloaf wrap it and freeze it.
Make a batch of meatballs in a crockpot. When they're done I let them cool. Then I take three meatballs and put them in a zip lock bag along with some sauce. Freeze them. You can take them out for a sub or to have with ziti, spaghettie, etc.
I buy a large package of hamburg. (What I usually do is if their's a roast on sale I have it ground for hamburg) Okay, so what I do is divide it up. I scramble some so I can use for a meatpie, american chop suey, tacos, etc. I fry it up and also bag that as well or put it into a plastic container. I usually divide it up so I have enough for a meal in each container.
I also will take a large/family size package of bonless chicken breast. Marinade for a day or so then cook it on the grill. When it's done I let it cool and wrap each piece individually. That way you can put in on a salad, make fajitas,etc.
What I always do when I make and freeze food is I always label each bag, etc. along with the date I made it.
Hope this helps.
