What can I do with too many zucchinis?
This is the perfect recipe for when you have an abundance of zucchini and summer squash. This recipe is great with just zucchini or if you have it yellow summer squash too.
I also have recipes for Baked Kale and Zucchini Pilaf, Gluten Free Summer Squash Casserole and Gluten Free Zucchini Chocolate Chip Cookies that are all great options for your extra zucchini.

Should you peel zucchini?
Fresh zucchini should have a very soft skin that doesn't need to be peeled. If your zucchini has a hard skin it is likely old or over ripe. If possible, I would choose a different zucchini to cook with and compost the over ripe zucchini with tough skin.
Most of the nutrition is in the deep green skin of the zucchini squash, which makes it a great reason to leave the peel on.
