In a large bowl, toss together the potatoes, oil, salt, and thyme until the potatoes are coated in all ingredients. Spread the potatoes in an even layer on the baking sheet and bake for about 20 minutes or until soft, stirring the potatoes about halfway through.
For the Salmon
While the potatoes are cooking, line a baking sheet with foil and spray with nonstick spray. Keep the oven set to 400 degrees.
In a small bowl, combine all the ingredients except the salmon, and mix well. Lay the salmon skin-side down on the baking sheet and brush the curry mixture over top. Let sit for about 5 minutes and then bake the salmon for 10 to 15 or until the fish is flaky and firm. Serve with potatoes on the side.
