Ingredients
Directions
Preheat an outdoor grill for medium-high heat and lightly oil the grate.
Combine mushrooms, onion, zucchini, yellow squash, and bell peppers in a large bowl. Add teriyaki, garlic, and ground pepper. Toss to thoroughly coat vegetables with the sauce; be gentle with the onion to keep it intact.
Place vegetables on the grill and cook, turning once, until vegetables begin to soften, 5 to 10 minutes.
