This is one of those easy to put together appetizers/sides that will become a go-to in your repertoire…
It’s naturally vegan, except for the cheese topping which can easily be replaced with a scattering of nutritional yeast. It’s a wonderful side for a dinner of soup or stew, a warm late afternoon snack after a winter walk, or to be shared with a glass of wine while the fire crackles. While those all sound like cozy times, it is after all a zucchini recipe and is a fabulous addition to a summer dinner on the patio!
