In a small bowl, combine the mustard powder, salt and sage. Brush the steaks with oil and sprinkle over the sage salt, reserving a little to scatter at the end.
Set a large nonstick frying pan over a medium to high heat and cook the steaks for 2-2 1/2 minutes on each side for a medium-rare steak. Add another minute for a medium to well-done steak. Remove the steaks from the pan and loosely cover with foil. Leave to rest for 5 minutes.
Using kitchen towel, remove any steak juices from the pan, then heat the butter over a medium heat. Add the garlic and mustard and cook for 30 seconds, stirring well to combine. Add the kale and cook for 3 minutes, stirring until wilted.
Divide the kale between 2 plates, lay over the steaks and sprinkle over the reserved sage salt.
Tip: For a perfectly grilled steak, let the meat sit at room temperature for 20-30 minutes.
