Preheat and prep: Heat the oven to 425°F (220°C). Line a sheet pan with parchment for easy cleanup.
Season the sweet potatoes: Toss cubes with 1.5 tablespoons olive oil, smoked paprika, garlic powder, cumin, a pinch of chili powder (if using), and a good pinch of salt and pepper.
Roast the vegetables: Spread sweet potatoes on the sheet pan.
Roast for 12 minutes, then add sliced bell pepper and red onion with the remaining 0.5 tablespoon oil and a pinch of salt. Roast 12–15 minutes more, until potatoes are tender and edges are caramelized.
Season the chicken: Pat chicken dry. Rub with 1 teaspoon olive oil, salt, pepper, and a light sprinkle of smoked paprika and garlic powder.
Cook the chicken: Use a hot skillet over medium-high heat.
Sear 5–6 minutes per side, until the thickest part reaches 165°F (74°C). Rest 5 minutes, then slice. (Or roast on a second sheet pan for 18–20 minutes.)
Make the sauce: Stir Greek yogurt, lemon juice, grated garlic, and olive oil. Season with salt and pepper.
Thin with a splash of water if needed.
Build the base: Add a handful of greens to each bowl, or scoop in warm cooked rice or quinoa. You can use half greens, half grains for balance.
Layer the toppings: Add roasted sweet potatoes, peppers, and onions. Top with sliced chicken, avocado, and pumpkin seeds or almonds.
Finish and serve: Drizzle with the yogurt sauce, sprinkle with herbs, and add a squeeze of lemon or lime.
Taste and adjust salt or acidity.
