Preheat oven to 425°F. Peel and cube sweet potatoes, then toss with olive oil, salt, pepper, and paprika. Spread on baking sheet and roast for 25-30 minutes, shaking halfway through.
Pat chicken dry and season both sides with salt, pepper, and garlic powder.
Heat olive oil in a large skillet over medium-high heat. Cook chicken 4-6 minutes per side until browned. Remove from skillet.
Reduce heat to medium. Add maple syrup, Dijon mustard, soy sauce, chicken broth, and garlic to skillet. Stir and scrape browned bits, simmer for 1-2 minutes until thickened.
Return chicken to skillet, spoon sauce over it, and cook for 2-3 minutes to absorb flavors. Let chicken rest briefly and then slice.
Assemble bowls with mixed greens, cooked quinoa or rice, roasted sweet potatoes, and sliced chicken. Drizzle extra sauce on top.
Garnish with optional toppings such as avocado, pecans, or green onions. Serve warm with lemon wedges.
