Step 1
Preheat oven to 425°F. In a large bowl, combine the potatoes, 1-1/2 tablespoons of the olive oil and the thyme and season with salt and pepper. Spread on a sheet pan, cut sides down and roast 15 minutes.
Step 2
While the potatoes are roasting, in the same bowl, combine the leeks, asparagus, salt and pepper and the remaining 1-1/2 tablespoons of the olive oil. Toss to combine. After the potatoes have roasted for 15 minutes, turn the potatoes with a thin spatula and add the leeks and asparagus to the sheet pan. Roast 10 minutes longer.
Step 3
While the vegetables are roasting, toast the almonds in a dry pan until lightly golden, about 5 minutes. Set aside.
Step 4
Season fish with salt and pepper. In a small bowl, combine the honey mustard with 2 teaspoons of water. Put the fish on top of the vegetables tucking the tails under and brush with the honey mustard. Sprinkle with the almonds and roast until the fish is opaque or registers 145°F. in the center, about 12 minutes. Sprinkle with the chives and serve with lemon wedges.
