Thanks to my new couponing habit (inspired by Teresa), I bought a bunch of zucchini and yellow squash that were on sale. I decided to use them up in Ina Garten's Zucchini Gratin. I had everything on hand except the onion, so I decided to leave it out since Joe doesn't care for it anyway. I may have compensated for lack of onion with some extra cheese. :-)
We really enjoyed this dish. It might make it into the regular rotation ... as long as zucchini or squash is on sale.
