In a large bowl, drizzle about half of the Caesar dressing over the romaine lettuce. Gently toss until each piece is evenly coated.
Transfer the dressed lettuce to a serving platter or individual plates, creating a bed for the remaining ingredients.
Arrange the cooked shrimp on top of the dressed lettuce.
Sprinkle the freshly grated Parmesan cheese evenly over the salad.
Add the garlic croutons, distributing them throughout the salad.
If using optional ingredients like cherry tomatoes, avocado, or capers, arrange them across the salad.
Season with freshly ground black pepper and a light sprinkle of salt.
Drizzle the remaining dressing over the top of the salad, focusing primarily on the shrimp.
Garnish with fresh parsley if using, and place lemon wedges around the edge of the plate or bowl.
Serve immediately while the lettuce is crisp and the croutons crunchy.
