Kids and adults alike will love this quick and flavorful baked salmon with a light, crunchy crust. If matzoh isn't available, substitute any cracker crumbs.
Preheat the oven to 400 degrees.
Oil a large baking sheet and set aside. In a small bowl, whisk together the mustard and mayonnaise. Season the salmon fillets all over with the salt and pepper. Brush the top of each fillet with some of the mustard mixture and sprinkle generously with matzoh crumbs, pressing them down to form a crust. Transfer the salmon, matzoh side up, to the prepared baking sheet and spray them again with oil. Bake until just cooked through, about 10 minutes.
