01 - Set the oven to 400°F (200°C) to prepare for roasting the squash.
02 - Toss the cubed squash with olive oil, ground cumin, smoked paprika, and a pinch of salt. Arrange in a single layer on a baking sheet and roast for 25 to 30 minutes, turning once halfway through, until tender and golden brown.
03 - Rinse millet under cold water. In a medium saucepan, bring 2 cups of water and ½ teaspoon salt to a boil. Stir in millet, reduce heat to low, cover, and simmer for 18 to 20 minutes until water is absorbed. Remove from heat and let sit covered for 5 minutes, then fluff with a fork.
04 - Whisk together tahini, lemon juice, maple syrup or honey, minced garlic, and enough water to reach a creamy, pourable consistency. Season with salt and black pepper to taste.
05 - Divide millet evenly among four serving bowls. Layer with roasted squash, sliced red bell pepper, halved cherry tomatoes, and baby spinach or arugula. Drizzle with the tahini dressing.
06 - Garnish each bowl with toasted pumpkin seeds and chopped fresh parsley if desired. Serve warm or at room temperature.
