Preheat oven to 450º cut potatoes in half lengthwise; cut each half lengthwise into 1 inch wide wedges.
Place potatoes in a large bowl; toss with oil, press garlic, sprinkle with seasoning; toss to coat evenly. Spread potatoes in a single layer and roast 12-15 minutes and turn potatoes, drizzle with balsamic and roast additional 12-15 minutes or until golden brown and crisp-tender.
Broil peppers 4 in. from the heat until skins blister, about 5 minutes. With tongs, rotate peppers a quarter turn. Broil and rotate until all sides are blistered and blackened. Immediately place peppers in a large bowl; cover and let stand for 20 minutes.
Peel off and discard charred skin. Remove stems and seeds. Cut the peppers into thin strips; place in a large bowl. Add onion.
In a small bowl, whisk the oil, vinegar, herbs, garlic, garlic powder, cayenne, pepper and salt; pour over pepper mixture and toss to coat. Cover and refrigerate for up to 4 hours.
Before serving, allow peppers to come to room temperature. Place on a serving plate; top with tomatoes, cheese and basil leaves.
