Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Peel the sweet potato and cut it into 1/2-inch cubes.
In a bowl, toss the sweet potato cubes with 0.5 tbsp of olive oil, 0.25 tsp of sea salt, and the smoked paprika.
Spread the potatoes in a single layer on the baking sheet and roast for 20-25 minutes until tender and caramelized.
While the potatoes roast, season the chicken tenderloins evenly with garlic powder, the remaining 0.25 tsp of sea salt, and black pepper.
Heat the remaining 0.5 tbsp of olive oil in a large skillet over medium-high heat.
Add the chicken tenderloins to the skillet and sear for 3-4 minutes per side until golden brown and cooked through to an internal temperature of 165°F.
Remove the chicken from the skillet and set aside; in the same pan, add the minced garlic and sauté for 30 seconds until fragrant.
Add the fresh spinach to the skillet and toss constantly for 1-2 minutes until just wilted.
To serve, place the wilted spinach on a plate and top with the roasted sweet potatoes and pan-seared chicken tenderloins.
