01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - Place the halved bell peppers cut side down on the baking sheet. Roast for 20 minutes, or until skins are blistered and charred. Remove from oven, cover with foil, and let steam for 10 minutes. Peel off and discard the skins, then slice peppers into strips.
03 - While peppers roast, bring 2 cups water to a boil in a saucepan. Stir in bulgur, cover, reduce heat to low, and simmer for 10-12 minutes or until tender. Fluff with a fork and let cool.
04 - In a small bowl, whisk together miso paste, olive oil, rice vinegar, honey (or maple syrup), and soy sauce to make the glaze.
05 - In a large bowl, combine the cooked bulgur, roasted pepper strips, red onion, cherry tomatoes, and parsley. Pour over the miso glaze and toss gently to coat.
06 - Transfer to a serving platter. Sprinkle with toasted sesame seeds and feta cheese (if using). Serve at room temperature or lightly chilled.
