I've been reading a book called How To Cook a Wolf. One of these blogs I read mentioned it and I picked it up last week, used of course.

It is written by a woman trying to feed her family with some dignity during the rations of WWII. It is chock full of amazing stuff. The main things I've taken away from it right now though is:
Instead of eating balanced meals, eat a balanced day.
Altho I aim for $30 a week I actually am closer to $37 a week. I never eat out, at least not on my own dollar, at least not while I'm trying to pay off the 20% mortgage.
Every 3 weeks I cook a whole fryer ($2-5 depending on sales.) Then I make chicken soup from it (About $8.50 for all ingredients.) That soup covers 15 small lunches at work. (It is a wonderfully frugal trait to be able to eat the same thing every day.) My other meal at work is leftovers, or a sandwich or peanut butter and saltines. I like to make a breakfast sandwich 3-4 times week as well. My other breakfasts might just be a yogurt, or thick sliced toast with cream cheese or a banana.
Today I've eaten two small bialys (tiny bagels) sandwiches that a friend was going to throw away at the beach last night. I had some carrots, (I buy a 2 pound bag of real carrots, peel and slice them and put them in a pot with a very small amount of water, a pat of butter and a squirt of honey. That'll give me 4 veggie sides for work for $1.49.) And I have a chicken soup defrosting behind me for dinner.
I'm learning that some meals only need to give you enough sustenance to get to the next meal.
One of my other favorite tricks is to go to the deli counter and make the person slice two slices of some meat and two slices of some cheese, (you get a sample slice too so that is three of each really,) and then head to the bakery and buy one roll. I walk out with a "deli sandwich" that only costs $1.40 or so instead of the $5.99 sandwich they sell there.
BTW, I call this the mortgage diet. I've lost 17 pounds since closing. Trim the fat indeed!
