Shrimp Caesar Salad

Ingredients:
Nonstick cooking spray
4 slices whole-grain bread
1 tablespoon canola oil
1 pound raw shrimp, shelled and cleaned, tails removed
1/2 teaspoon salt
1/4 teaspoon black pepper
2 tablespoons lemon juice
4 tablespoons light mayonnaise
1 teaspoon Worcestershire sauce
4 tablespoons finely grated Parmesan
1/4 teaspoon garlic powder
8 cups torn romaine lettuce
1/2 cup thinly sliced red onion
4 tablespoons shaved Parmesan

Directions:
Preheat the broiler. Mist a shallow baking sheet with cooking spray. Brush the bread lightly on both sides with the canola oil; cut into 3/4-inch cubes. Place in a single layer on the sheet and broil until lightly browned, about 1 minute per side. Transfer croutons to a plate and let cool.
Toss the shrimp with salt and black pepper and place in a single layer on the same baking sheet. Broil 2 minutes per side or until just cooked through.
In a bowl, whisk together the lemon juice, mayonnaise, Worcestershire, grated Parmesan, garlic powder, and 2 tablespoons water.
Toss the lettuce, onion, and croutons in a bowl; drizzle dressing over the top and toss to combine. Spoon shrimp on top; garnish with shaved Parmesan.
