Heat 1 tbsp oil in skillet over med-high; sauté stir-fry carrots + salt/pep 3-4 min; add sauce packet, cover + cook 1-2 min more until tender

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 cooked through

Divide barramundi + veggies between plates—that was easy!
