Microwave potatoes in bag 6-7 min; let cool 1-2 min + chop into quarters, season with 1 tbsp oil + salt/pep

Meanwhile, pat fillets dry + add 2 tsp seasoning; heat 1 tbsp oil in skillet over med-high, add to pan + sear 5-6 min until fish naturally releases from pan; flip + cook 1-2 min more until cooked through

Heat 1 tbsp oil in large skillet over med-high + sauté half the spinach with salt/pep 1-2 min until wilted; add rest of spinach + cook 1-2 min until all is wilted; divide everything between plates + top fish with 2 tbsp tzatziki—looks great!
