In a bowl combine the salt, pepper, paprika, garlic powder, and thyme.
Place the salmon on the lined sheet pan and sprinkle all of the spice blend over the salmon and bake for 12 minutes.
While the salmon is baking heat the balsamic vinegar and honey until they boil. Mix a tbsp of water with the cornstarch and bring to a boil until it has thickened.
Remove the salmon from the oven and brush the glaze over the top. Bake for another 3 minutes or until the salmon has cooked all the way through.
