In a small bowl, add olive oil, parmesan cheese, red wine vinegar, lemon juice, garlic, dry mustard powder, Worcestershire, anchovy paste, and pepper. Mix well.
Preheat the grill to high heat.
While the grill is heating, cut each romaine heart in half lengthwise. Lightly spray the cut side with olive oil and season with salt and pepper.
Place the romaine on the grill cut side down, and cook 2-3 minutes or just until lightly seared.
Arrange the romaine cut side up on a serving plate. Drizzle the dressing overtop followed by the Parmesan cheese and crispy capers.
Notes
Cut the romaine hearts in half lengthwise so the leaves remain attaches to the stem.
Leave stems on during cooking to keep each half intact.
Romain hearts should just be lightly seared for no more than 2-3 minutes. Don't overcook.
*Capers are drained and fried in oil on medium-high in a pan until crispy and golden brown. Drain on a paper towel.
