Preheat oven to 400 degrees and lightly oil a sheet pan or spray with non-stick cooking spray.
Add potatoes to a mixing bowl and toss with 1 tbsp. olive oil, Italian seasoning, and salt and pepper.
Add the potatoes to the pan, cut-side-down, and roast for 15 minutes.
While the potatoes are cooking, add the garlic, kale, and 1 tbsp. olive oil to a mixing bowl.
Use your hands to massage the olive oil into the kale. Then, toss the garlic and kale together.
Remove pan from the oven and push the potatoes to one side of the pan.
Add the kale and salmon to the empty side of the pan. Place pan back into the oven and cook for 15 minutes more, or until the potatoes are fork tender, the kale is crispy, and the fish is cooked through.
Divide the salmon, potatoes, and kale between two plates and serve.
