How to Make It
Heat grill to medium-high. Once it is hot, clean the grill grate with a wire brush. Just before grilling, oil the grill grate.
Combine the tomatoes, anchovies, parsley, garlic, 3 tablespoons of the oil, and ¼ teaspoon each salt and pepper in a medium bowl.
Season the steaks with ½ teaspoon each salt and pepper. Grill until an instant-read thermometer inserted into the center of each steak registers 130° F, 2 to 3 minutes per side for medium-rare. Let rest for 5 minutes before slicing.
Rub the bread with the remaining tablespoon of oil. Grill until golden brown, 1 to 2 minutes per side.
Serve the steak and bread with the tomato salad.
