Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Peel the sweet potatoes and cut them into 1/2-inch cubes.
Toss the sweet potato cubes with 0.5 tablespoon of melted ghee and a pinch of sea salt on the prepared baking sheet.
Roast the sweet potatoes for 20-25 minutes, tossing halfway through, until they are tender and slightly caramelized.
While the potatoes roast, season the chicken breast on both sides with sea salt, black pepper, garlic powder, and dried oregano.
Heat the remaining 1 tablespoon of ghee in a large skillet over medium-high heat.
Place the chicken in the skillet and pan-fry for 6-7 minutes per side, or until the internal temperature reaches 165°F and the surface is golden brown.
Steam the broccoli florets for 4-5 minutes until they are vibrant green and fork-tender.
Plate the pan-fried chicken alongside the roasted sweet potatoes and steamed broccoli, adding the chilled sauerkraut to the side for a fermented finish.
