Preheat your oven to 450 degrees. Spray an oven-safe baking pan with non-stick spray (or coat pan with oil).
In a small bowl, combine the chili powder, oregano, and salt. Mix to combine. Sprinkle spices on top of the pieces of cod. Press spices slightly into the fish to adhere. Place the seasoned cod into prepared baking pan.
Bake at 450 degrees for about 10 minutes, or until fish is done and opaque in color.
While the fish is baking, make the sauce to top the cooked fish. Melt the butter in a small skillet. Add cumin and the juice of one lime. Stir to combine; cook for an additional minute. Remove from heat.
I think the sauce for this recipe would also taste great on grilled halibut, swordfish, mahi-mahi, or tilapia.
