When you get into the habit of cooking and freezing you'll be amazed at how much easier dinner time will become. And, how automatically you'll start to think of ways to batch cook and save time. I've always had a second freezer so I can do this well and I highly recommend the purchase if you have a large family. You'll be cooking for quite a few years and you'll definitely get your money's worth from it! I also tend to cook more vegetables than I need and then use them in frittatas or fritters or an au gratin as a side for the next nights meal.
Note: I freeze rice in both large and smaller quantities. I use the large packs for an easy fried rice dinner or to serve up with curries or casserole. I measure exact quantities for some of my other recipes (For example, my rice-base for quiches) and this step saves me so much time in the preparation of another meal.
