1. Prepare and Roast the Chicken: Preheat oven to 425°F and line a large baking sheet with parchment. Blot chicken thighs dry with paper towels. Use kitchen shears to carefully remove the bone from each thigh, trimming around the joint and cartilage while keeping the meat intact. Place thighs skin-side up on the prepared baking sheet. Rub with olive oil and son generously with kosher salt and black pepper. Roast for 30–35 minutes, until the skin is golden and crisp and internal temperature reaches 165°F.
2. Roast the Veggies: In a small bowl, mix the cumin, paprika, nutritional yeast, chili powder, and kosher salt. Place the cubed butternut squash and cauliflower florets on a second sheet pan. Drizzle with olive oil and toss with the soning blend until evenly coated. Roast in the oven for 20–25 minutes, until caramelized and tender.
3. Massage the Kale: While the chicken and vegetables roast, place torn kale leaves in a bowl. Add olive oil, lemon juice, and a pinch of kosher salt. Massage with your hands for 1–2 minutes until the leaves soften and turn dark green. Set aside.
4. Make the Lemon-Tahini Dressing: In a small bowl, whisk together tahini, lemon juice, olive oil, maple syrup, sesame oil, tamari, garlic, and kosher salt. Add water a tablespoon at a time to thin to your desired consistency. Taste and adjust soning if needed.
5. Assemble the Bowls: To each bowl, add a scoop of cooked brown rice. Top with massaged kale, a mix of roasted squash and cauliflower, and one crispy chicken thigh. Drizzle generously with lemon-tahini dressing and serve warm.
