Preheat your oven to 400°F and dice the sweet potato into small, uniform cubes.
Toss the sweet potato cubes with half of the olive oil, sea salt, and smoked paprika, then roast on a parchment-lined tray for 20 minutes until tender.
Season the chicken breast with garlic powder, sea salt, and black pepper, then pan-sear in a skillet over medium heat until golden and cooked through.
Prepare the couscous by adding it to a bowl with an equal amount of boiling water, cover, and let sit for 5 minutes before fluffing with a fork.
In a small jar, whisk together the lemon juice, lemon zest, and the remaining olive oil to create a bright, zesty dressing.
Assemble the bowl by layering the fresh baby spinach, fluffed couscous, roasted sweet potatoes, and diced red bell peppers.
Slice the chicken breast into strips, place on top of the bowl, and drizzle with the lemon-herb dressing before serving.
