Preheat your oven to 400°F for roasting the sweet potato.
Season the beef brisket generously with smoked paprika, garlic powder, salt, and pepper.
Sear the brisket in a hot skillet with olive oil for 2-3 minutes per side to develop a nice crust.
Transfer the brisket to a slow cooker or a covered dish with a splash of water and braise on low heat until tender (if using pre-cooked brisket, simply reheat with the seasonings).
Meanwhile, peel and cut the sweet potato into cubes, toss with a little olive oil, salt, and pepper, and roast in the oven for about 20-25 minutes or until tender and caramelized.
For the braised greens, lightly sauté kale in a pan with a small drizzle of olive oil, a pinch of salt, and a splash of water, allowing it to wilt and become tender.
Plate the dish by slicing the brisket, adding a serving of roasted sweet potatoes, and finishing with a generous serving of braised kale. Serve warm and enjoy the rich, smoky flavors.
