This is yummy and cooks quickly. It's a no fail recipe.
1 salmon fillet
Pre-heat oven to 400 F. While oven is pre-heating, sprinkle fillet with salt and lemon juice. When the oven reaches 400 F - place fish in a cooking spray coated baking dish. Drizzle fish with olive oil and sprinkle liberally with chile powder. Cook for 15-20 mins.
To check if fish is cooked through: Insert a knife into the thickest portion of the fish, count to 3, place flat of knife against your arm. If the knife is warm/hot the fish is done. Not warm? Fish needs more time.
