Preheat oven to 425 degrees Fahrenheit. Line your sheet pan with foil or parchment paper.
Slice your fingerling potatoes into halves, or thirds for particularly large potatoes. Very small potatoes can be left whole.
Add the potatoes, 1 tablespoon olive oil, thyme, salt, pepper, and ¼ teaspoon garlic powder to a bowl and stir to coat well.
Place the potatoes and thyme on the lined baking sheet. Place it in the oven and bake for 15 minutes.
Trim the asparagus, then add the tomatoes and asparagus to a bowl, drizzle with 1 tablespoon olive oil, and sprinkle with ¼ teaspoon garlic powder, salt, and pepper.
Season the salmon with salt and pepper.
Mix the Dijon mustard, sugar, and chipotle powder together. Then, brush the salmon with the mixture.
Remove the sheet pan from the oven.
Push the potatoes to one side of the pan and fill the remaining area with the asparagus, tomatoes, and salmon.
Bake for another 12 to 15 minutes depending on the thickness of your salmon. You want it to reach an internal temperature of 125 degrees Fahrenheit.
Remove from the oven and serve.
