Peppers of any kind are perfect for grilling. Bell, poblano, jalapeno, shishito etc. Zucchini or yellow summer squash Eggplant cut into thick rounds Onions - any type including green onions grilled whole Asparagus Broccoli - cut into large florets leaving most of the stem on. Cauliflower - cut into large pieces or "steaks" Mushrooms - especially portabello. Carrots - these don't get a lot of love as a grilled vegetable but the charring brings out a wonderful sweetness so I encourage you to try! Chose thin, fresh carrots for grilling. Corn on the cob is wonderful with a smoky charred flavour.
