Preheat the broiler. Brush both sides of the bread slices with olive oil and arrange on a rimmed baking sheet. Broil the slices 6 inches from the heat for about 3 minutes, turning once, until crisp and golden on the outside but still slightly soft in the center. Rub one side of each slice with the halved garlic.
In a medium bowl, whisk the minced garlic with the lemon juice, anchovy paste, mustard, Worcestershire sauce and capers. Gradually whisk in the 3/4 cup of olive oil and season the dressing with salt and pepper.
In a large bowl, toss the romaine with the Parmigiano-Reggiano and the dressing. Season with salt and pepper. Mound the salad on the toasts, garnished with shaved cheese.
