2 teaspoons dried dill, or to taste
Preheat oven to 375 degrees F (190 degrees C).
In a bowl, stir together mayonnaise and mustard. Stir in thyme, oregano, and basil. Place salmon fillets on a baking sheet, and spread with the mayonnaise mixture. Sprinkle with dill weed.
Bake in preheated oven for 30 to 40 minutes, until the salmon is easily flaked with a fork.
