Drizzle the olive oil into a pot over a highish heat, add your bacon followed by the garlic then cook for 3-4 minutes until they start to colour then add the butter and remove from the heat. Season the steaks.
In another pan heat a little sunflower oil,when the oil is smoking lightly cook your steak for 4 minutes on one side until it's nicely crusted, then turn over and cook for a further 3 minutes. This will give you a lovely pink steak.
Allow the steak to rest in a warm place whileyou cook the kale. Put the pot with the bacon and garlic back on the heat, add the kale with a splash of water and some salt & pepper.
Put a lid tightly on the pot and cook the kale for 4 minutes until it wilts and tenderises but still stays a lovely vivid green.
