Bring steaks to room temp and season with salt and pepper. Heat outdoor grill or indoor grill pan over medium-high heat or broiler. When you’re about ready to eat, dress meat with a drizzle of oil and cook steaks 4 minutes on each side for medium rare, up to 12 minutes, turning once, for well done.
Let meat rest while you combine chopped parsley or cilantro and zest of 1 lemon or 2 limes. Slice each steak thinly against the grain and dress sliced steaks with herb, garlic and zest mixture, the juice of 1/2 lemon or 1 lime, another drizzle of oil and a little more salt.
