Preheat your oven to 400°F (200°C).
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 0.25 tsp of smoked paprika.
Spread the cubes in a single layer on a parchment-lined baking sheet and roast for 20-25 minutes until tender and caramelized.
While the potatoes roast, pat the cod fillet dry with a paper towel and season both sides with garlic powder, the remaining smoked paprika, salt, and pepper.
Heat the remaining 0.5 tbsp of olive oil in a non-stick skillet over medium-high heat.
Place the cod in the skillet and sear for 3-4 minutes per side until the exterior is golden-brown and the fish flakes easily.
Place the chopped kale in a large bowl and massage it with a pinch of sea salt and a small squeeze of lime until the leaves are softened and dark green.
Assemble the bowl by placing the massaged kale at the bottom, followed by the roasted sweet potatoes and the crispy fish.
Garnish with the remaining lime wedge and serve immediately.
