Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Toss the cubed sweet potatoes with 0.5 tsp of olive oil and a pinch of the sea salt, black pepper, and garlic powder.
Spread the sweet potatoes in a single layer on the baking sheet and roast for 20-25 minutes until the edges are golden and crispy.
While the potatoes roast, pat the salmon fillet dry with a paper towel and season both sides with the remaining salt, pepper, and garlic powder.
Heat 0.5 tsp of olive oil in a non-stick skillet over medium-high heat and sear the salmon for 4-5 minutes per side until a golden crust forms and the fish is cooked through.
Remove the salmon from the pan and set it aside to rest.
In the same pan, add the final 0.5 tsp of olive oil and the chopped dino kale, sautéing for 2-3 minutes until tender and bright green.
Squeeze the fresh lemon juice over the kale and salmon before serving alongside the roasted sweet potatoes.
