Roast the Sweet Potatoes:
Preheat the oven to 400°F (200°C).
Toss the diced sweet potatoes with olive oil, smoked paprika, garlic powder, salt, and pepper. Spread them evenly on a baking sheet.
Roast for 25-30 minutes, flipping halfway, until golden and tender.
Cook the Chicken:
While the sweet potatoes roast, heat olive oil in a large skillet over medium-high heat.
Toss the chicken pieces with garlic powder, smoked paprika, cumin, chili powder, salt, and pepper.
Add the chicken to the skillet and cook for 6-8 minutes, stirring occasionally, until fully cooked and browned. Remove from heat.
Prepare the Dressing:
In a small bowl, whisk together olive oil, lemon juice, Dijon mustard, honey (if using), salt, and pepper. Set aside.
Assemble the Bowls:
Divide the cooked quinoa or brown rice among 4 bowls.
Top each bowl with roasted sweet potatoes, cooked chicken, baby spinach or kale, cherry tomatoes, red onion, and avocado slices.
Drizzle the dressing over each bowl.
