For our flavorful marinade you'll need some garlic, avocado oil, champagne vinegar, lemon, Italian seasoning, thyme, salt, and pepper. "I'm using avocado oil here since we'll be cooking at high heat, and it has a high smoke point," Hahn explains. Feel free to use another neutral oil like canola or vegetable.

Prep the zucchini and yellow squash

To prepare the squash for grilling, cut off both ends and discard. Then cut the squash in half lengthwise, then again into quarters. This is the perfect size spear for the grill and allows the marinade to penetrate the squash easily. Put the cut squash into a long container with a lid. While you have your knife out, mince the garlic.
