Preheat oven to 400 degrees F (200 degrees C). Oil a baking sheet or line it with aluminum foil.
Place salmon skin-side down on foil. Season it with salt, pepper and garlic powder.
Cover the fillets with a thin layer of mustard.
Melt butter. Mix Panko with melted butter and spread the mixture on the fillets.
Bake in a preheated oven for 15 minutes, or until salmon flakes easily with a fork.
If you don't want to melt the butter, just top the Panko with cold pieces of butter. It will melt in the oven.
If you want to save some calories, skip the butter.
If you turn on the broiler at the end for about 1 minute you will have a super crunchy crust and more color.
You can use a spicy mustard for more flavor.
