Making things from scratch can save you TONS of money, and lots of things are easier to make then you would think. I always buy my hamburger in bulk, that way I can separate it into hamburger patties and meatloaves. This way you are paying $8 for 20 patties, instead of $20 for 8 patties!
It is also great because you can customize it with your own ingredients and make them proportionate to your family size. Be sure to watch the video posted above to see how I make mine (takes about 20 minutes from start to finish) and how I am able to sneak veggies in that my kids may not necessarily eat.
