Preheat your oven to 400°F (200°C).
Peel the sweet potato and cut it into 1/2-inch uniform cubes.
Toss the sweet potato cubes with half of the olive oil, smoked paprika, and a pinch of the sea salt.
Spread the potatoes on a parchment-lined baking sheet and roast for 20-25 minutes until tender and slightly caramelized.
While the potatoes roast, season the chicken breast with garlic powder, black pepper, and the remaining sea salt.
Heat the remaining olive oil in a skillet over medium-high heat.
Add the chicken to the skillet and sear for 6-7 minutes per side, or until the internal temperature reaches 165°F.
Remove the chicken from the heat and let it rest for 3 minutes before slicing into thin strips.
Place the baby spinach in a large bowl and top it with the roasted sweet potatoes and sliced chicken.
Finish the bowl by adding the sliced avocado, pumpkin seeds, and a fresh drizzle of lemon juice.
