Drizzle 3 halibut steaks with olive oil and sprinkle both sides with 1 tablespoon of Ancho chili powder, 1 teaspoon of garlic powder, salt and pepper.
Place empty cookie sheet in oven and heat broiler on high for 10 Minutes. This will get the pan very hot so the fish cooks from both sides.
Place halibut steaks on the hot cookie sheet and broil for 6 Minutes.
Take a butter knife and insert vertically into the thickest part of the fish for 5 seconds and remove.
Carefully and quickly tap the flat side of the knife to your lip to test the temperature.
If the knife is warm it is ready to serve, if still cold you will need to cook a minute more.
Remove halibut from pan and serve with side of choice.
