Preheat oven to 400°F; slice ½ the bag of potatoes in half lengthwise, mix with halved brussels + 2 tbsp oil, salt/pep + fave spices (we like garlic powder), then spread on a sheet pan cut side down; roast 25-30 min until tender

Meanwhile, pat fish dry, line a small baking dish with foil, spread 2-4 tbsp sauce on fish + salt/pep; bake 10-12 min until firm, opaque + cooked through

Divide halibut + veggies between 2 plates + drizzle with 1-2 tbsp sauce—that looks delish!
