Preheat oven to broil. Toss bread cubes in 1 tablespoon of oil and 1/2 teaspoon of salt. Spread evenly on a rimmed baking sheet. Broil in the center of the oven until crispy, about 1-3 minutes. Remove croutons to a plate and set aside.
Turn broiler off, and oven on to 400 F. Toss shrimp in remaining tablespoon of oil, and sprinkle with 1 teaspoon of salt and 1/2 teaspoon of pepper. Spread into a single layer on the same rimmed baking sheet and bake in the oven until cooked through, about 8-10 minutes.
Meanwhile, combine the dressing ingredients together in a small blender, or shake really well in a salad shaker.
Assemble the salad, and drizzle the dressing on top. Enjoy!
