Yes, classic lasagna is delicious, but when we're craving something a tad less carb-heavy, we turn to this summery zucchini version.

For this recipe, we ditched the canned cream of mushroom soup, and went for fresh instead.

Cook the mushrooms enough that they get a little caramelized and you'll really be good to go.

Never fear, this lightened-up green bean casserole is here to help you save room for pumpkin pie. Forgoing canned cream of mushroom for a quick homemade mushroom gravy, we'd argue this version is healthier and more delicious than the classic.
