Microwave 2 potatoes in their wrappers on high, 6-8 min, flipping over halfway through cook time (caution, that's a hot potato!); carefully cut in half, then set aside

Meanwhile, pat fish dry, season with salt/pep + seasoning pack; heat 1 tbsp oil in skillet over med-high (get that pan hot, otherwise the fish will stick) + sear fish 3 min, flip + sear another 1-2 min (for well done cook 3 min on second side)

Heat 1 tbsp oil in large skillet over med-high; sauté half the spinach + salt/pep 1-2 min until wilted; add remaining spinach + cook 1-2 min more until all spinach is wilted

Divide ingredients to 2 plates
