Make the dressing. In a small blender or food processor, blend the Greek yogurt, parmesan, garlic, capers, dijon mustard, lemon zest, lemon juice and black pepper.
Cook the shrimp. Preheat a skillet over medium-high heat. Toss the shrimp with olive oil, salt and pepper, then transfer to the skillet and cook until shrimp is opaque, 2 to 3 minutes per side.
Make the croutons. Preheat oven to 400°F. On a baking sheet, toss cut bread with oil, salt, pepper and garlic powder. Bake until golden brown, 5-10 minutes.
Assemble salad. In a large bowl, toss the romaine lettuce with the dressing, shrimp and croutons. Serve immediately.

Notes
Storage: Store all ingredients (lettuce, shrimp, & dressing) separately and combine once you're ready to make a salad fresh.
