Preheat your oven to 400°F and line a baking sheet with parchment paper.
Dice the sweet potato into 1/2-inch cubes and toss them in a bowl with 0.5 tsp of olive oil, 0.125 tsp of sea salt, and the smoked paprika.
Spread the sweet potatoes in a single layer on the baking sheet and roast for 20-25 minutes until tender and caramelized.
While the potatoes are roasting, slice the chicken breast and tempeh into thin, bite-sized strips.
Season the chicken and tempeh with the garlic powder, black pepper, and the remaining sea salt.
Heat the remaining 0.5 tsp of olive oil in a large non-stick skillet over medium-high heat.
Add the chicken strips to the skillet and cook for 5-7 minutes, turning occasionally, until golden brown and cooked through.
Add the tempeh strips to the same skillet during the last 3 minutes of cooking to allow them to brown and become fragrant.
Assemble your bowl by layering the roasted sweet potatoes at the bottom, followed by the seared chicken and tempeh.
Top the bowl with a generous scoop of cold sauerkraut and serve immediately.
