Summer produce fresh from the farmers market or your own garden is one of life’s true pleasures. The season is fleeting, though, so be sure to enjoy it while you can. There are many recipes for squash casserole and every one I’ve tried has been delicious. Here is a simple version that only requires one skillet and one baking dish. Because summer is too short to spend washing unnecessary dishes!

Delicious!
This makes a wonderful side dish but I happen to like it as the star dish of an all-veggie dinner. Pick out the best looking vegetables at the farmers market and enjoy a plate of summer goodness. I recently served this along with baked potatoes, whiskey-glazed carrots and a nice green salad. I then enjoyed the leftovers for my lunch the next couple of days.
