One of the fun things of being frugal is waste, you try to avoid it at all costs.
I try to use left overs for lunches, etc. One of my favorite things to do though, is to use all of something expensive. Cory loves asparagus, it's close to being in season here, but still pretty costly.
What I do, is I save those pesky ends, I cut them up and include them in soups, risotto, or casseroles. If I can't use them right away, I flash boil & freeze them. I use broccoli ends, asparagus, etc.
It's using everything possible, to save money & stretch your dollars.
