One of the things I love to do is take leftovers and get another meal or two out of them...eg ham then ham sandwiches, ham n beans, etc.
The other nite I made a big kettle of "stuffed peppers" and made extra meatballs to cook along with the peppers...saved the leftovers and the tomato juice broth and meatballs in fridge. Next nite had pizza and bread stix from local pizza joint...tonite mashed up leftover meatballs in tomato broth, making meat sauce to use in homemade lasagna, served with leftover bread stix...course this requires liking italian two or three nites in a row

Excluding junk food we spend around $250.00/month for 2 people.
And believe me, we eat extremely well.

My very favorite budget recipe is this:

Save every piece of left over veggies (except potatoes) for a month or so. Have a large plastic container in the freezer and just dump the leftovers every night on the top. At the end of the month take it out, add a large can of tomato juice (or V8) or veggie stock with water, a couple of diced potatoes and a few carrots and some browned ground beef, if desired. Throw into the crockpot and let 'er rip for the day on low. Make some cornbread and you have a very delicious meal.
