Frugal Potato Chips?

Snacks like potato chips are not only pretty unhealthy, they can also put a HUGE dent in our food budget. So I rarely buy them.
Of course, that doesn't mean my kids don't ever ask for them!
I was about to peel some potatoes and cook them (to make mashed potatoes), when I had an epiphany! Instead of throwing out the peels (I don't put potato peels in my soup stock veggies), I could save them and make potato peel crisps!
So I scrubbed the potatoes, and peeled them right into my pyrex baking pan. Then I mixed the peelings with about 1 T. of olive oil and a sprinkling of salt, and baked them in my toaster oven at 400 - 425 F, until they are all brown and crisp! And they taste very yummy!
Have you ever done this?
