Preheat oven to 400°, mix halved brussels with 1 tbsp oil + season with salt/pep + seasoning pack; place on a sheet pan + roast 17-25 min until golden + tender

Meanwhile, tear corner of rice to vent + heat in microwave 90 sec (careful—it'll be hot!)

Pat fillets dry + season with salt/pep; heat 1 tbsp oil in skillet over med-high (get that pan hot, otherwise the fish will stick); add to pan skin-side down + sear 5-6 min undisturbed until fish naturally releases from pan; flip over + cook 1-2 min until fish is cooked through

Divide trout, halved brussels + rice between plates with a squeeze of lemon onto trout—looks great!
