Remove the steak from the refrigerator about 20 minutes before cooking, so that it can come to room temperature. This will help the steak cook more evenly. Preheat a grill pan or outdoor grill over medium-high heat.
In a small bowl combine the paprika, salt and pepper. Generously season the steak with the spice mix. Put on the grill pan and cook until medium-rare, about 4 minutes on each side. Remove from the pan to a cutting board and allow to rest for 5 minutes. Slice against the grain into 1/2-inch thick strips and arrange on a serving platter. Serve topped with tango sauce.
Put all the ingredients, except the olive oil, in the bowl of a food processor or blender and pulse to combine. With the machine running, stream in the olive oil until well incorporated. Serve with the steak.
