Rinse and chop the romaine lettuce into bite-sized pieces. Place it in a large salad bowl and set aside.
Pat the shrimp dry with paper towels. In a small bowl, toss the shrimp with olive oil, garlic powder, salt, and black pepper until evenly coated.
Heat a skillet over medium-high heat. Add the seasoned shrimp and cook for 2-3 minutes per side, or until pink and opaque. Remove from heat and set aside.
Drizzle the Caesar dressing over the chopped romaine lettuce. Toss gently to coat the leaves evenly.
Add the cooked shrimp, grated Parmesan cheese, and croutons to the salad. If desired, squeeze fresh lemon juice over the top for extra brightness.
Toss the salad once more to combine all ingredients. Divide into two portions and serve immediately. Enjoy your Caesar salad with shrimp!
