Preheat oven to 400°. Toss prepped vegetables with sesame oil. Place vegetables on parchment-lined sheet pan and roast 20 min, turning over halfway through. Remove from oven when softened and turn broiler to high.
For the miso glaze, combine white miso paste, ginger, sesame oil, soy sauce, rice vinegar and ground black pepper. If thick, add water to thin, then brush glaze onto vegetables. Broil 3-5 min to caramelize the miso glaze. Turn veggies, as needed, and watch closely to avoid scorching.
Remove from oven, plate and garnish with sesame seeds. Serve immediately with Kefir Kombucha Sauce, a quick whisk together of kefir, Stinging Kombucha hot sauce and pinch salt and pepper.
