Ingredients for grilled zucchini and squash

There’s not much you need besides the vegetables here! This grilled zucchini and squash is very basic, but uses just the right ingredients to get big flavor. On their own both are very bland, but amp them with these Italian seasonings and they taste incredible. Here’s what you need for grilled zucchini and squash:

Medium-sized zucchini: You’ll want a zucchini that’s not too small or too big. Zucchini or summer squash that are too large can get stringy and seedy.
Medium-sized summer squash: Same notes as for the zucchini!
Dried basil and oregano: to bring in the Italian flavor
Garlic powder and onion powder: rounds out the amazing flavors
Olive oil & kosher salt
