Lots and lots of "drop bags".
Basically, all of the ingredients for a meal ready to drop into the slow cooker.
So, I'll buy a large amount of pork, let's say. Portion it out into the right sized for 4 people, put into a sealable freezer bag, along with everything else needed for the meal. Might be peppers, onions, tomatoes, soy sauce, spices, you get the idea. Then, freeze, uncooked.
The night before I want that meal, get the bag out of the freezer and drop the whole think I to the slow cooker. In the morning, when defrosted, open up the bag, pour out and set the slow cooker off.
There are only two of us that eat meat, so two meals + two to use later in the week.
I like this method, so I don't end up with masses of the same meal frozen.
