Thaw shrimp if frozen, pat dry, and season with salt, pepper, and garlic powder. Preheat grill to medium heat (about 350°F). Grill shrimp for 2-3 minutes on each side until pink and slightly charred.

Mix Caesar dressing in a bowl with a dash of lemon juice for brightness. Adjust creaminess to preference and set aside.

Lay a tortilla flat and add romaine lettuce, followed by grilled shrimp. Drizzle Caesar dressing and sprinkle with Parmesan.

Add optional bacon bits or croutons for extra crunch. Consider adding crushed red pepper or Cajun seasoning for a kick.

Fold sides of tortilla in and roll tightly from the bottom. Place seam-side down and serve immediately.
