Tonight I went grocery shopping.  In case any of you wonder how much it costs to feed a family of 5 (6 on the weekends, not counting the extra sons) healthy food for a week, the total was $106.  Mind you, the pantry was not bare, but I did get snacks.  People often complain about organic food being expensive, but when you are not buying expensive pre-processed junk food, there is room in the grocery bill for the good stuff. 
I also try to save money by buying the larger size of packaged items and using the item in several dishes.  For instance, the small size organic, prewashed spinach was $2.99.  For $3.99, I got twice as much of the same product.  That's enough spinach for a couple of big salads, veggie lasagna, and sauteed spinach.
Another money-saver is making extra at dinner time and eating leftovers for lunch the next day.  I just bought myself a new lunch bag, glass lunch-sized storage containers, and a thermos.  I am getting good use out of them, and enjoying the convenience of having dedicated containers for my lunch.  It encourages me to pack my lunch the night before instead of grabbing what I can in the mornings.
