If you are really rambunctious try this for your future enjoyable easy eats: freeze small batches of lasagne, leftover pork ribs (these re-heat in the oven most excellently), turkey and fixin's (remember Thanksgiving?) and casseroles--or leftovers in general. Freezing leftover red sauce for pasta is a gift from heaven when tired or sick. You can cook extra chicken when grilling so that it can be defrosted in the refrigerator and you'll have a ready source of sandwich makings or salad add-ins (or casseroles for that matter). There is also the satisfaction of having something at hand to put in the oven on a night when you don't feel like preparing stuff for dinner!
To keep your frozen food safe you must follow good freezing practices. Excellent general advice on such is to be found here: freezing at the NCHFP
If you want to freeze prepared foods, like the lasagne I mentioned above or casseroles try the NCHFP's Freezing Casseroles, Soups and Stews. This is the ultimate in convenience food: your good cooking in your freezer!
For a good booklet (you might want to print up) about freezing all sorts of prepared foods try Preserving Food: Freezing Prepared Foods. You will need a .pdf reader. The foods it covers range from biscuits to whipped cream, and it has a good list of foods that do not freeze well. This is a good and valuable reference to have around the house.
Preserving by freezing requires some organization, just like preserving by canning, but if you can jar fruits and veggies to process, you may certainly freeze other, un-jar-able items as well. As mentioned above, they can be the most convenient foods--sometimes it is nice to be able to throw something in the oven for dinner and not even need to crack open some jars to do so.
