Preparation

• Position a rack in the center of the oven and heat to 350°F.
• In a small bowl, mash 2 Tbs. of the butter and the blue cheese. Set aside.
• Pat the steaks dry and season with salt and pepper. Heat the oil in a large skillet over medium-high heat. add the steaks and cook, flipping once, until nicely browned, about 4 minutes. Reserving the skillet, transfer the steaks to a small baking sheet and roast until medium rare (130°F to 135°F), 3 to 5 minutes. Let rest for 5 minutes.
• Meanwhile, arrange the endive in one layer in the skillet. Dot with the remaining 2 Tbs. butter and drizzle with the honey. Cover and cook over medium heat, stirring occasionally, until tender, about 5 minutes. Season to taste with salt and pepper. Arrange the steaks and endive on a platter. Slather the steaks with half of the blue cheese butter, and drizzle lightly with additional honey, if you like. Sprinkle with the walnuts and chives, and serve.
