Thaw halibut and pat dry.
In a small bowl, combine orange juice, lime juice, garlic powder, onion powder, salt, & pepper.
Add halibut to a ziploc bag and pour orange juice marinade over. Allow it to marinade for 25-40 minutes.
Preheat the grill to medium-high heat.
Place the halibut on foil and grill the halibut for 10-12 minutes with a second piece of foil on top.
While the halibut cooks, prepare the other bowl ingredients.
Once cooked, assemble the bowl with the grilled halibut.
Serve and enjoy!
