In a bowl, mix together the Green & Black’s cocoa powder, espresso, coconut sugar, chili, garlic, oregano, salt and pepper.
Score both sides of the steak by making a diamond pattern of shallow cuts. Rub the steak generously with the spice mix and set aside.
Heat the oil in a large cast iron skillet over high heat until super hot. Add the steak and cook for about 4 minutes per side for rare. Once cooked, allow it to rest on the cutting board, tented, for at least 5-10 minutes.
Meanwhile, pulse the almonds and parsley in a food processor until they reach a coarse ground up consistency. Transfer to a bowl and stir in the Green & Black’s Organic chocolate, cheese, oil and salt and pepper, to taste.
To serve, slice the steak thinly against the grain and top with a sprinkle of fleur de sel. Serve with the pesto garnished with a shaving of lemon zest. Enjoy!
