A great summertime casserole using yellow squash and zucchini. But if the little zucchini buggers are taking over your house, it's o.k. to use all zucchini in this recipe! :)

This was great!! There was an omission of how much onion but all good cooks can wing it

One word, YUMMY! This is the best ever! I forgot to salt and pepper but it was still awesome. I could have eaten all of it but after my weightless surgery, I could only eat a small serving. I didn't change the recipe because it is perfect as is!

Even the non-veggie eating son loved this. I only had yellow squash and no mushrooms. Steamed for few minutes instead of cooking them up with butter. I also used fat free soup mix and low fat sour cream. Mixed everything together and threw in the pan. Will be using this recipe again.
