Preheat oven to 425° and line a baking sheet with parchment paper. Set aside. Also get a pot of salted water and bring to a boil.
In a small bowl combine the dijon mustard, garlic, lemon juice, lemon zest, rosemary, honey, salt, pepper and crushed red pepper. In another bowl, combine the panko, walnuts and olive oil.
Place salmon on prepared baking sheet and pat them dry with a paper towel. Spoon the dijon mixture over the fish, full coating each piece. Then sprinkle the panko mixture over the top and lightly press down to adhere to fish. Spray the tops with a little cooking spray.
Bake until fish flakes with a fork, about 9-12 minutes.
While the salmon is baking, cook the orzo to package instructions. Then strain. Add the butter and parsley to the still warm pot and let melt. Then add in the lemon juice and lemon zest. Return the orzo to the pot, give it a stir and season with salt and pepper to taste. Add cooked broccoli if desired.
To serve, spoon the orzo in the bottom of a shallow bowl and place the salmon on top. Garnish with a lemon wedge and fresh parsley. Enjoy!
