Sheet Pan Dijon Salmon and Sesame Panko Potatoes

1. Preheat oven to 450°F. 
2. On a baking sheet, toss the potatoes with 2 tablespoons melted butter. Season with salt and pepper. Roast for 15 minutes, or until tender. 
3. Meanwhile, whisk together both mustards, the lemon juice, shallot, cayenne, thyme, salt, pepper, and 4 tablespoons melted butter. 
4. Grab the potatoes from the oven. Toss with panko, sesame seeds, and garlic. Add the salmon to the baking sheet, then pour 1/2 of the dijon dressing over the salmon. Bake for 10 minutes, or until the salmon reaches your desired doneness. During the last minute, switch the oven to broil and broil until lightly charred. Watch closely.
5. In a bowl, toss the arugula/shaved asparagus and dill with 1-2 tablespoons of the dijon dressing. Season with salt and pepper. 
6. Spoon the remaining dressing over the salmon. Serve the salmon and potatoes topped with greens. Enjoy!
