Preheat oven to 450 F on broil. Spread corn on a silicone mat (make sure your mat is rated for 450 degrees). Set mat on tray on top shelf of oven. Broil for 10-12 minutes or to desired doneness. In my oven this takes 12 minutes but keep an eye on it.
Chop bok choy (or cabbage) and red peppers. Add some water to a pan and turn on medium heat. Add veggies and lightly season with salt, paprika, and cumin. Saute until water has evaporated and veggies have reached desired doneness and caramelization. If water disappears before theyre done, add some more water or put a lid on the pan to finish cooking.
After removing corn, set oven to bake at 425 F.
Rinse and pat dry fish. Rub with spice mixture. Finally, coat both sides with sumac.
Coat bottom of pan with a little olive oil and add fish. Bake for 6 minutes per 1/2 inch thickness. It should flake easily at the thickest point, and the internal temperature should be 140 F.
Plate and enjoy. Top with chopped tomatoes or pico de gallo.
