Hi N.,
With the tip of freezing chicken broth, freeze them in your muffin tins, then once frozen, you can take them out of the tins and put them into a large freezer bag. This way, you are not chiseling away at a huge block of chicken broth for one meal.
Another idea is to double (or triple) whatever you are making now and put the second one in the freezer with a label so you'll know what it is... For example, instead of placing that lasagna into a 9 x 13 pan, cook it in two smaller pans, especially if your family does not eat it all at one sitting. Or double the recipe, and then cook it in three equally proportionate pans--that way, you have two extra meals when you've only put forth a little bit of effort to double what you are making for tonight's meal...
Yet another fun idea is to get together with some of your friends and do a meal swap. Each of your friends (say in a group of 7 friends) makes a meal--or at least the main entree. But, instead of making only one of it, make 7. Then, you get together on a specific day and trade--each of you leaves with 7 different meals..and all you had to do was to cook one specific meal. (It's easier to do assembly line and make lots of one type of meal than to think about 7 different type of meals...). Don't forget to put instructions on the foil--such as "cook for 45 minutes at 350".
Good luck with this fun challenge and with your upcoming baby! You'll do well. :-)
