01 - Preheat the oven to 400°F.
02 - Toss butternut squash and red onion with 1 tablespoon olive oil, turmeric, cumin, smoked paprika, cinnamon, salt, and pepper. Spread on a baking sheet and roast for 25 to 30 minutes, stirring halfway, until caramelized and tender.
03 - Heat remaining 1 tablespoon olive oil in a medium saucepan over medium heat. Add millet and toast for 2 to 3 minutes, stirring until fragrant.
