The combination of both squashes is colorful and the most asked for as a side dish when the first harvest is ready.
We love all kinds of squash all year long and in the fall butternut is on the top of our list of must makes with our butternut squash soup and then acorn squash with cinnamon butter roasted, both are family favorites and so delicious.
During the summer we use lots of zucchini to make Zucchini Bread, or another favorite using this wonderful vegetable is Zucchini Roll-ups. We also love making Fried Zucchini as an appetizer then dipped in a fresh marinara sauce, that's so addicting.
This recipe is perfect for a lighter meal, especially during warmer weather.
I will even give you some other suggestions to add for a whole meal instead of just a side dish.

What's The Difference Between Yellow and Green Squash?
Besides the color, the main difference between the two vegetables is the shape.
Zucchini is virtually straight while the yellow squash is oddly shaped.
Yellow squash has a large bulb-like fat bottom then tapers towards the neck.
Yellow squash can also have more seeds in its flesh.
Flavor-wise, both are mild-tasting with a hint of vegetable sweetness.
Either way, both are perfect for this dish and interchangeable, use all of one or mix them up, it won't matter whatsoever!
