Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Slice the carrots into 1/2-inch thick rounds and toss them on the baking sheet with half of the olive oil, a pinch of sea salt, and black pepper.
Roast the carrots for 20 minutes until they begin to soften.
While carrots roast, season the chicken breast with garlic powder, the remaining sea salt, and black pepper.
Heat the remaining olive oil in a skillet over medium-high heat and sear the chicken for 6-7 minutes per side until fully cooked.
Drizzle the pure maple syrup over the partially roasted carrots, tossing to coat, and return them to the oven for another 5-7 minutes until caramelized.
Place the fresh baby spinach on a plate, top with the sliced cooked chicken and the warm maple-glazed carrots.
Garnish with chopped walnuts for a satisfying crunch and serve immediately.
