Preheat the oven's broiler and coat a baking sheet or broiling pan with olive oil.
Rinse the fish and pat dry. Place on the greased pan, and brush with olive oil or coat with olive oil cooking spray. Squeeze the juice from the lemon wedges over the entire fillet, and season generously with salt first, then pepper and finally dill.
Broil for 10 minutes in the preheated oven, until the fillet is opaque and can be flaked with a fork. Broiling time may depend on the thickness of your fillet.
