Heat 1 tbsp oil in skillet over med/high; pat both steaks dry, season with salt/pep + sear undisturbed 2-3 min; flip + cook an additional 2-3 min for med-rare (for more well done, add 1-2 min per side); rest steaks 5 min

Heat 1 tsp oil in large skillet over med-high + sauté half the spinach + salt/pep 1-2 min until wilted; add remaining spinach + ½ the butter, cook 1-2 min more until all spinach is wilted + butter is melted

Divide steaks + spinach to plates—bon appétit!
