Heat a grill pan over medium-high heat. Season steaks with salt and pepper. Brush grill with oil. For medium-rare, grill steaks for 3 minutes on each side, rotating one-quarter turn after 1 1/2 minutes on each side to produce crosshatch marks. As the steak is cooking, use a paper towel or a brush to lightly dab with oil. Top each steak with a slice of herb butter. Serve with frites.
